I-Fiberglass Mat vs. Woven Roving: Yeyiphi i-Reinforcement efanelekileyo ekwakheni iinqanawa?

Ngena nakweyiphi na ivenkile ethengisa izinto zaselwandle uze ucele “i-fiberglass,"Uze ufumane ukujonga okungenanto kulandelwe ngumbuzo othi: i-fiberglassimathi okanyeolukiweyoukuhambahambaUninzi lwabantu abakha okanye abalungisa isikhephe okokuqala abazi nokuba kukho ukhetho abamele balwenze. Bathenga nje nantoni na enikwa ngumntu osemva kwekhawuntara, kwaye ngamanye amaxesha oko kusebenza kakuhle, kwaye ngamanye amaxesha akwenzeki.

Imathi enqunqiweyo yentambokwayeukuzulazula okulukiweyo zezona mpahla zimbini oza kudibana nazo kakhulu kumsebenzi wenqanawa yokubeka izandla. Nangona kunjalo, azingomkhuphisani—zisetyenziswa kunye, kwiindawo ezithile, ngezizathu ezithile. Ukuzixuba, okanye ukutsiba enye ngokupheleleyo, yindlela eqhelekileyo abantu abagqibela ngayo benesinqe esibonakala silungile unyaka okanye emibini size siqale ukubonisa ushicilelo okanye, okubi ngakumbi, sibe yi-delaminates.

Nantsi into eyahlulahlula ngokwenene.

I-Strand Mat eqoshiweyo

Imathi enqunqiweyo yentamboyimigca yeglasi emifutshane, i-intshi enye okanye ezimbini ubude, isasazeke kwiindlela ezingacwangciswanga kwaye ibanjwe kunye nge-binder—nokuba yi-powder binder okanye i-emulsion binder. Ayibalulekanga kangako kwiinjongo zethu ngaphandle kokuba ifuna i-resin esekelwe kwi-styrene (i-polyester okanyei-vinylester) ukuze inyibilike ngokufanelekileyo. Oku kuyabakhubekisa abantu ngaphezu kokuba ucinga. I-Epoxy ayiwaphuli umxokelelwane ngendlela efanayo, ngoko ke ukuba uzama ukulayita imathi nge-epoxy, ungagqibela unesiphithiphithi esiqinileyo nesimanzi kancinci esingaze sidibane kakuhle.

Yenziwe ngokusika ifayibha yeglasi eqhubekayo uze uyibeke ebhantini apho i-binder ibeka khona ipateni engacwangciswanga. Akukho ndlela ilungileyo, akukho luko — iifayibha ezisasazekileyo kuyo yonke indawo. Uya kuyibona rhoqo kwi-1.5 oz, 2 oz, okanye 3 oz nge-square foot, kwaye i-1.5 oz yinto abantu abaninzi abafikelela kuyo xa besenza umsebenzi we-hull.

Into emalunga ne-mat kukuba isela i-resin. Ininzi kakhulu. Ujonge into efana nomlinganiselo weglasi ukuya kwi-resin we-25/75, oko kuthetha ukuba i-laminate egqityiweyo inzima kunokuba ubuya kulindela ngobungakanani beglasi ekuyo. Oko kuvakala kubi, kwaye ngamandla amsulwa ngepawundi nganye, kunjalo. Kodwa loo nto ifanayo yiyo eyenzaimathi enqunqiweyoilungile kwimisebenzi eyisebenzayo—ihambelana neegophe eziqinileyo kunye neekona ezinokuthi ilaphu elilukiweyo eliqinileyo lizidibanise, kwaye izalisa ipateni yokuluka erhabaxa ukuze ingaprinti kwi-gelcoat yakho.

Ukuzulazula okulukiweyo

Izinto ezahluke ngokupheleleyo. Endaweni yemicu enqunqiweyo engacwangciswanga,ukuzulazula okulukiweyoyimiqulu yefayibha yeglasi eqhubekayo elukiweyo ibe ngelaphu—ulwelo oluqhelekileyo, oluyi-0 kunye ne-90 degrees, olufana ne-burlap kodwa lwenziwe ngeglasi. Ungaziva iintambo zomtya ngeminwe yakho.

Ubunzima budla ngokuba yi-18 ukuya kwi-24 oz ngeyadi yesikwere. Izinto ezinzima ngakumbi — uluhlu lwe-24 oz — zibonakala emazantsi eenqanawa nakweyiphi na indawo eza kuthatha umthwalo okanye impembelelo yolwakhiwo.

Ngenxa yokuba imicu isebenza rhoqo endaweni yokuba inqunyulwe ize isasazeke, ukuzulazula kunamandla kakhulu ngepawundi nganye kune-mat. Ikwafuna i-resin encinci ukuze imanzise kakuhle, kufutshane ne-50/50 glass-to-resin, ngoko ke ugqibela une-laminate ekhaphukhaphu neyomeleleyo enomlinganiselo ofanayo weglasi. Ingxaki kukuba ayifuni ukugoba kwiigophe eziqinileyo—yityhale iye kwikona ebukhali, ize ivale, ishiye isithuba esingaphantsi ongayi kuyibona de i-gelcoat iqhekeke phezu kwayo kwiminyaka kamva. Ikwashiya ubume obubonakalayo bokuluka ukuba uyibeka phantsi kwengubo yokugqiba, yiyo loo nto ungayenzi loo nto.

Ngoko ke ngowuphi ongcono ngokwenene?

Akukho nanye kwezi, kwaye loo nto ayisosiso isicombululo. Buza nawuphi na umakhi obeke iinqanawa ezingaphezu kwezimbini, kwaye baya kukuxelela into efanayo: usebenzisa zombini, ngokutshintshana kweeleya, kuba zenza imisebenzi eyahlukeneyo.

I-fiberglass rukuhambahambauthwala umthwalo.Iglasi yefayibha matIdibanisa iileya kunye kwaye ikunika umphezulu ogudileyo apho kubalulekile khona. Tsiba imathi phakathi kweeleya zokuzulazula ukuze wonge ixesha okanye izinto, kwaye uzibeka esichengeni seengxaki eziphakathi kwelaminari—iileya azinxibelelani ngaphandle kokuba kubekho into ezalisa izikhewu phakathi kwe-coarse weave.

Ishedyuli eqhelekileyo ngokuchasene ne-gelcoat ihamba ngolu hlobo: kuqala i-mat (iyayeka ukuprinta), emva koko ijikeleze, ize i-mat kwakhona, itshintshana amaxesha amaninzi njengoko i-layup ifuna. Umaleko wokuqala uhlala u-mat, nokuba yintoni enye oyisebenzisayo, kuba ukuhamba ngqo ngokuchasene ne-gelcoat phantse kuhlala kufikelela kwiigrafu ekugqibeleni.

Apho Nganye Isetyenziswa Khona Ngokwenene

Giimathi zefayibha yelass Yinto onokukhetha kuyo nayiphi na into enemiqolo eqinileyo—iitshini, iintambo, kunye neekona ze-transom—kuba zolula kwaye zikrazuke ngesandla kwaye zihambelana ngaphandle kokulwa. Kwakhona yinto oyifumanayo kwiindawo ezincinci zokulungisa apho ungadingi mandla amaninzi okwakha, kodwa ufuna nje ukubopha okuhle kunye nokugqitywa okugudileyo.

Ifayibha yeglasi rukuhambahambaIya apho isakhiwo sibaluleke khona ngokwenene: ii-hull bottoms, ii-transoms, ii-bulkheads, naphi na apho kuya kuguquguquka okanye kube nefuthe. Ukuba ubunokuhambahamba kuphela kwaye ungenamathe, ubuya kugqibela une-laminate eqinileyo ngokwethiyori kodwa inamabala abuthathaka phakathi kweeleya, kunye neepateni ezibonakalayo zokuluka kuyo yonke indawo kufutshane nomphezulu. Ayisiyondibaniselwano intle.

Iindlela ezimbalwa abantu abaphosisa ngazo oku

Ukusebenzisai-epoxyUkuba ne-mat ebotshelelwe kwi-polyester resin mhlawumbi yeyona mpazamo ixhaphakileyo endiyibonayo—i-binder ayinyibiliki ngendlela ekufanele inyibilike ngayo, kwaye ufumana i-laminate ebonakala ilungile ide inganyibiliki.

Ukutsiba imathi yefiberglass phakathi kweengqimba zokuzulazula yenye into enkulu, edla ngokwenziwa ukuze kongiwe ixesha lokulungiswa. Isenokuhlala ixesha elide. Ikwayenye yezona zizathu zixhaphakileyo zokuba ii-hulls ezindala ezilungisiweyo ziqale ukuqhekeka.

Kwaye ke kukho ukukhetha ubunzima belaphu ngokusekelwe kwinto ehleli eshelufini kunokuba kuxhomekeke kwinto efunekayo kwicandelo lokwenyani. Isiseko sehakethi kunye nekhabhathi ayingomsebenzi ufanayo. Ukuziphatha ngendlela efanayo kuchitha ubunzima apho ungabudingiyo okanye kunciphise ubunzima apho ubudinga khona.

Iimpendulo ezikhawulezayo kwimibuzo eqhelekileyo

Isukuzulazula okulukiweyoInamandla kune-mat? Ngeponti nganye, ewe, ngomda olungileyo—iifayibha eziqhubekayo zithwala umthwalo ongcono kuneentambo ezinqunqiweyo ezisasazekileyo. I-mat ayikho apho ukuze iqine; ikhona apho ukuze ibotshelelwe khona kwaye igqitywe phezu kwayo.

Ungawutsiba umethi uze usebenzise i-roving? Ungakwenza, kodwa ibangela ingxaki kuyo nayiphi na into eyakhiweyo. Ngaphandle kwemethi phakathi kweeleya, ulahlekelwa ngamandla aphakathi kwe-laminar, kwaye mhlawumbi uza kubona indlela ipateni yokuthunga iqhubeka ngayo ekugqibeleni.

Yeyiphi indibaniselwano efanelekileyo yokulungisa isiqu? I-mat ichasene nomphezulu, ijikeleza ukuze iqine; i-mat kwakhona ukuba ufuna ukwakheka okungakumbi. Ishedyuli echanekileyo ixhomekeke kubukhulu kunye nendawo yento oyilungisayo—akukho mpendulo ichanekileyo inye egubungela yonke into oyilungisayo.

Ingongoma ephambili: le ayisiyongxaki "xa kuthelekiswa" nangona umbuzo udla ngokubuzwa. I-fiberglass mat kunye ne-loven roving zisombulula iingxaki ezahlukeneyo, kwaye uninzi lomsebenzi wesikhephe esiqinileyo usebenzisa zombini, ngokulandelelana ngokuchanekileyo, kwiindawo ezifanelekileyo. Khetha ophumeleleyo, kwaye uza kugqibela une-laminate enzima kakhulu kwaye ibuthathaka okanye inamandla kodwa izele ziindawo ezibuthathaka ezifihlakeleyo. Zisebenzise ngendlela ezimele zisetyenziswe ngayo, kwaye akufuneki ukhethe konke konke.
