I-Vinyl Ester Resin: Oko Kwandifundisa Iminyaka Engama-35 Kwimijelo Yomsele Ngokuyifumana Ngokufanelekileyo

Bendisoloko ndisebenza kwii-composites ukusukela ngo-1989. Iminyaka engamashumi amathathu anesihlanu ndiphefumla i-styrene, nditshisa iminwe yam kwi-laminate exotherming, kwaye ndisebenzisana nabathengisi abathembisa ihlabathi kwaye bathumela inkunkuma. Ukuba ufunda oku, mhlawumbi uyakufunai-vinyl ester resinngento ebalulekileyo. Itanki yeekhemikhali. Inqanawa yesikhephe. ​​Umbhobho wokucoca. Ndiza kukuxelela into endiyifundileyo malunga nokufumanaumthengisi we-vinyl ester resin ngubani ongayi konakalisa iprojekthi yakho. Ndinezimvo. Andizukuzithambisa.

Yeka ukudideka nge-ester ye-vinyl kunye ne-polyester

I-resin ye-vinyl esterngumzala we-epoxy. Uthatha umqolo we-epoxy uze uwusebenzise nge-methacrylic acid. Amaqela e-ester aphelela kwisiphelo se-chain kuphela. Yiyo loo nto yonke ingqiqo yemolekyuli. Amaqela ambalwa e-ester athetha ukuba kukho iindawo ezimbalwa zokuhlasela ze-asidi kunye ne-alkali.

I-Polyester inee-ester ezininzi kulo lonke uthotho. Yiyo loo nto iitanki ze-polyester ziqhekeka emva kweminyaka emihlanu zisebenza ngeekhemikhali. Iitanki ze-vinyl ester zingamashumi amabini. Ndizichole zombini. Umahluko awubonakali kangako.

Ndibabukele abathengi benxibe i-isophthalic polyester kuba “ikufutshane ngokwaneleyo.” Ayikufutshane ngokwaneleyo. I-Isophthalic yi-resin elungileyo. Ayinjaloi-vinyl ester resinUkuba umthengi wakho ukhethe i-vinyl ester uze uthumele i-iso polyester, uza kubanjwa. Uvavanyo lwelabhoratri luthatha imizuzu elishumi elinesihlanu. Emva koko igama lakho likwingxelo yokusilela. Musa ukuyenza loo nto.

I-Epoxy iyenza ngcono kune-vinyl ester ephepheni. Enyanisweni, i-epoxy ibiza kabini, ifuna ii-ovens emva kokulungiswa, kwaye ii-laminators zakho aziyithandi ukusebenza ngayo.I-resin ye-vinyl esteriinkqubo eziphantse zifane ne-polyester. Ungayibeka ngesandla, uyitshize, uyikhuphe, uyisebenzise kwi-RTM. Yiloo nto ukuguquguquka kokucubungulai-vinyl ester resinIlawula imarike yokugqwala ephakathi. I-Epoxy ineendiza. I-Polyester ineempahla ezingabizi kakhulu. I-vinyl ester ineento zonke eziphakathi.

Ingxoxo yexabiso Akukho mntu ufuna ukuba nayo ngokunyaniseka

Nantsi intoumenzi we-vinyl ester resininene iyabiza. I-ester ye-vinyl eqhelekileyo ye-bisphenol-A isebenza phakathi kwe-2,800 ukuya kwi-3,500 ngetoni nganye. I-ester ye-vinyl ye-Novolac epoxy — ekumgangatho ophezulu wobushushu — ikwi-3,800 ukuya kwi-4,500. I-Epoxy iqala kwi-4,500 kwaye inyuke idlule kwi-7,000. I-polyester ye-Ortho ingaphantsi kwe-$1,800.

I-resin ye-vinyl esteriindleko ziphantse ziphindwe kabini kunexabiso le-iso polyester.

Kodwa kwi-30% ye-sulfuric acid, i-vinyl ester ihlala ixesha elide ngokuphindwe kathathu ukuya kahlanu.

Ndikhuphe ii-cores kwi-tank yeekhemikhali kunyaka ophelileyo. Iminyaka elishumi elinesihlanu ndisebenza. I-vinyl ester liner yayisaphelele. Itanki efanayo, i-polyester backup liner, iimeko ezifanayo zenkonzo. Ndingawuqhekeza loo resin ye-polyester ngobhontsi wam nomnwe wam.

Ngoko ke xa umphathi wezinto endixelela ukuba i-vinyl ester ibiza kakhulu, ndibuza umbuzo omnye. Ixabisa malini itanki xa ingaphumeleli? Ukucoca okusingqongileyo kukodwa kudla ngokuphindwe kalishumi kunexabiso le-resin. Ityala liphezulu. Izibalo zilula. Abantu abafuni ukukwenza kuba inani elingaphambili libonakala likhulu kwi-PO.

Entleumthengisi we-vinyl ester resinIkunceda wakhe loo bhokisi yobomi. Elibi libiza ixabiso ngekhilogram nganye lize linyamalale.

Umrhwebi okanye uMenzi — Funda Ukwahlula

Isiqingatha seenkampani ezikwiiplatifomu ze-B2B zizibiza ngokuba “ziinkampani ezizimeleyo”.umthengisi we-vinyl ester resin"ngabarhwebi. Abanayo i-reactor. Abanayo ilebhu. Bathenga kumzi-mveliso othenga i-epoxy komnye umzi-mveliso. I-resin ibonakala kwidokhi yakho enamanani ebhetshi angahambelaniyo ne-CoA. Ukuqina kunciphile ngama-40%. Ufowunela ukukhalaza. Akukho mntu uphendulayo.

Nantsi indlela yokuzisusa ngokukhawuleza.

Cela iifoto zereactor ezinomhla wangoku kwiphepha elikwifoto. Cela imveliso yenyanga ngeetoni zemetric. Cela iiCoA ezivela kwiibhetshi ezintathu ezilandelelanayo. Inyaniumenzi we-vinyl ester resinuphendula le mibuzo ngoko nangoko. Umrhwebi uthi “mandikujonge ndize ndibuye.” Eso sivakalisi sikuxelela yonke into.

Ndityelele “umenzi” ngo-2019 owayenewebhusayithi entle ebonisa iholo ye-reactor engenabala. Ndafika ubuso ngobuso. Indawo yayiyi-warehouse eneedrums ezibhalwe ngokutsha. Akukho reactor. Akukho lab. Indoda enye enefowuni. Ndaphuma. Umntu endikhuphisana naye akazange aphulukane nayo. Ulahlekelwe yi-$80,000 kwi-batch embi eyaphuma kwi-drum ngexesha lokuthunyelwa. “Umthengisi” wayivala inombolo yakhe.

Iipropati Ezibalulekileyo Emgceni Wevenkile, Hayi Kwincwadana

Andikhathali ngephepha ledatha. Ndikhathali ngento eyenzekayo xa i-resin ingena kwi-mold.

Ukuqina. Ukuba ingaphezulu kwe-500 mPa·s kwi-25°C, ii-laminator zakho ziya kulwa nokumanzi xa zilukiwe. Ziya kuyinciphisa nge-styrene. Ngoku uyinciphisile i-resin. Iipropati ziyawa. Umthengisi uyakugxeka ngokongeza i-styrene. Usola umthengisi ngokuthumela i-resin etyebileyo. Ndiyibukele le ngxoxo isenzeka izihlandlo ezilikhulu. Isisombululo silula. Thenga kwiumenzi we-vinyl ester resinolawula i-viscosity ephakathi kwama-200 nama-400 mPa·s. Ngokuqhubekayo.

Ixesha lejeli. Ndisebenze nebhetshi enye emva kokuba ijeli ityiwe ngemizuzu eli-12 kubushushu bevenkile obungama-35°C. Imizuzu elishumi elinesibini. Awunakubeka i-manway fitting ngemizuzu elishumi elinesibini. Udinga imizuzu engama-25 ukuya kwengama-40 yokusebenza ukuze wenze umsebenzi onzima wokubeka izandla.umthengisi we-vinyl ester resinkufuneka ulungise iphakheji yomxhasi ukuze ihambelane nevenkile yakho. I-cobalt naphthenate engaphezulu kwiivenkile ezibandayo. Incinci kwezishushu. I-BPO ukuba uphilisa ngaphantsi kwe-15°C. Ukuba umthengisi akanakukwazi ukulungisa inkqubo yonyango, bakuthengisa ifomula emiselweyo kwaye balindele ukuba uyenze isebenze. Oko kungasemva. I-resin iyasebenza kuwe. Awusebenzeli i-resin.

Ubunzima beBarcol. Kufuneka bufikelele kuma-35 ukuya kuma-40 kwiiyure ezingama-24 kubushushu begumbi. Ukubambeka kuma-28 emva kweentsuku ezimbini kuthetha ukuba kukho into engalunganga. Nokuba ipesenti ye-MEKP ayisebenzi, okanye i-resin indala, okanye i-promoter yonakele ngenxa yokugcina kakubi. Ndiyibonile i-resin "entsha" eyayineenyanga ezilishumi elinesibhozo ubudala kuba yayikwindawo yokugcina impahla eshushu yomsasazi. I-promoter yayisele iqalile ukusabela ngaphakathi kwidrama. Ufumana ukuphiliswa okucothayo kunye nemiphezulu enamathelayo engasoze iqine ngokupheleleyo.

Apho Ndibone khona iVinyl Ester Win — Nalapho Abantu Bachitha Imali

Ndichazilei-vinyl ester resinkwiitanki zokugcina iikhemikhali, imibhobho yokucoca, ii-marine hulls, iipayipi ezigqunywe phantsi komhlaba, kunye neeprofayili zesakhiwo eziqhekekileyo. Iyasebenza. Isebenza kakuhle kakhulu kwinkonzo yokubola naphi na apho ufuna khona ubomi boyilo beminyaka engama-20.

Izityalo zeekhemikhali. Yiyo leyo inkulu.I-resin ye-vinyl esteryinto eqhelekileyo yokubeka i-lining yezinto zokukhusela ezinye. Ukuba wakha itanki ephethe i-30% ye-hydrochloric acid, akukho ndlela ingabizi kakhulu ehlala ikhona. Ndiza kutsho ngokucacileyo oko.

I-Marine. Amanzi anetyuwa atya i-polyester. I-vinyl ester ihlala ihleli amashumi eminyaka. Abakhi beenqanawa abakrelekrele basebenzisa i-vinyl ester kulusu lwangaphandle olungaphantsi komgca wamanzi baze batshintshele kwi-polyester kwisakhiwo sangaphakathi. Ufumana umqobo wokugqwala apho uwudinga khona. Ugcina imali apho ungayifuniyo khona.

Kodwa nantsi apho ndicaphuka khona. Ndibone iinjineli zichaza i-vinyl ester kwitanki yamanzi kubushushu obuqhelekileyo. Amanzi. Ubushushu begumbi. I-Iso polyester iphatha loo nto iminyaka engamashumi amabini ngesiqingatha sexabiso. Ndixelela abathengi oku nokuba kuthetha ukuba ndithengisa i-resin encinci. Ukuba ucacisa kakhulu, uchitha imali yabathengi bakho. Ekugqibeleni bayayifumana loo nto baze bafumane umntu oza kunyaniseka kubo.

Indawo yokugcina izinto iya kubulala inzuzo yakho

I-resin ye-vinyl esterinobomi beshelufu beenyanga ezi-3 ukuya kwezi-6 kumaqondo obushushu angama-25°C. Ngalinye i-10°C ngaphezulu linciphisa ubomi beshelufu ngesiqingatha.

Ndibone abathengi beodola isitya esipheleleyo, besibeka kwindawo yokugcina izinto ezenziwe ngesinyithi ngoJulayi, ndize ndizibuze ukuba kutheni i-resin ingena kwidrama emva kweeveki ezisibhozo. Ubushushu bubulala i-vinyl ester. Umkhuthazi uqala ukusabela. I-viscosity iyanyuka. Ngenye intsasa uvula idrama kwaye iqinile.

Ukuba yakhoumthengisi we-vinyl ester resinIinqanawa ezivela phesheya, ulahlekelwa ziiveki ezi-3 ukuya kwezi-4 zobomi beshelufu xa usendleleni. Irhafu itya enye iveki. Indawo yakho yokugcina impahla ihlala phezu kwayo inyanga yonke. Usenokuba neeveki ezintandathu zobomi obusebenzisekayo xa uvula idrama yokuqala.

Oda ubungakanani obuncinci rhoqo. Ixabiso ngekhilogram linyuka kancinci. Ulahla i-resin encinci kakhulu. Nditshintshe umthengi ukusuka ekuhanjisweni kweetanki ezinkulu ukuya kwii-tote ze-IBC zenyanga. Inkunkuma yakhe yehle ukusuka kwi-12% ukuya ngaphantsi kwe-2%. Izibalo zisebenze kakuhle.

Iziqinisekiso azikhethi

I-ISO 9001 ngumgangatho. Ukubaumenzi we-vinyl ester resinakabambeki, yiphelise incoko.

Ukuthunyelwa eYurophu? Ufuna ubhaliso lwe-REACH. Akukho REACH, akukho mvume yerhafu. Ndibukele yonke isitya somthengi sibanjwa eRotterdam kangangeeveki ezintathu. I-resin yayingenazo iimpepha ze-REACH. Iindleko ze-Demurrage zidlule ixabiso le-resin. Umthengisi wanikina amagxa.

Izicelo zaselwandle zifuna imvume yohlobo lwe-DNV okanye lwe-ABS. Amanqaku athintela ilangabi afuna i-UL 94 V-0. Qinisekisa ukuba isatifikethi sigubungela amanqanaba athile owathengayo. Ndibafumene ababoneleli bebonisa isiqinisekiso se-UL somgca wemveliso eyahlukileyo kwaye ndinethemba lokuba andizukuqaphela. Ndiqaphele.

Oko Ndikuxelela Wonke Umthengi Omtsha

Fumana iumenzi we-vinyl ester resinovavanya yonke ibhetshi aze athumele i-CoA ngaphambi kokuba ubuze. Ingcali yekhemistri kubasebenzi kufuneka iphendule ifowuni xa i-resin yakho inganyangeki. Ukupakisha kufuneka kuhlale iiveki ezintathu kwisikhongozeli. Amaxwebhu kufuneka afike ngaphambi kokuba uwalandele.

Oda uvavanyo kuqala. Ngamaxesha onke. Itoni enye ukuya kwezintlanu. Yisebenzise kumgca wakho wokuvelisa. Hayi ilebhu. Ilebhu iyaxoka. Umgangatho wevenkile uxela inyani. Bhala phantsi ixesha lejeli kubushushu bevenkile yakho. Jonga ukuba imanzi kangakanani na kwi-reinforcement yakho. Beka ixesha lokucoca. Khangela indawo ebambekayo kunye namehlo eentlanzi kumphezulu wejeli.

Emva koko thelekisa intloko nentloko nayo nayiphi na into oyisebenzisayo ngoku. Ukuba i-resin entsha iphola ngokukhawuleza, imanzi ngcono, kwaye umphezulu ucocekile, umfumene umthengisi wakho. Ukuba kukho naziphi na kwezo zinto zimbi, qhubeka ukhangela.

Ndisebenze neabathengisi be-vinyl ester resinezivela eTshayina, eIndiya, eYurophu, nase-US. Ezilungileyo zikho kuyo yonke indawo. IJografi ayichazi umgangatho. Ulawulo lweenkqubo luchaza umgangatho. Umzi-mveliso oqhutywa kakuhle eShandong udlula umsebenzi ongekho semgangathweni eStuttgart. Ndizibonile zombini.

I-resin engabizi kakhulu ayikaze ibe yi-resin engabizi kakhulu. Ndafunda oko ngo-1997. Ndayihlawulela ngetanki elahlekileyo kunye nomthengi onomsindo kakhulu. Isifundo asitshintshanga kwiminyaka engama-28. Musa ukuyifunda ngendlela endiyifundileyo.
