Izinto eziqiniswayo yi-skeleton exhasayo yemveliso ye-FRP, eyona nto imisela iimpawu zomatshini wemveliso ye-pultruded. Ukusetyenziswa kwezinto zokuqinisa kwakhona kunempembelelo ethile ekunciphiseni ukucutheka kwemveliso kunye nokwandisa ubushushu be-thermal deformation kunye namandla aphantsi kwempembelelo yokushisa.

Kuyilo lweemveliso ze-FRP, ukukhethwa kwezinto zokuqinisa kufuneka kuthathelwe ingqalelo ngokupheleleyo inkqubo yokubumba imveliso, kuba uhlobo, indlela yokubeka kunye nomxholo wezinto eziqinisayo zinempembelelo enkulu ekusebenzeni kweemveliso ze-FRP, kwaye ngokusisiseko zinquma umatshini. amandla kunye ne-elastic modulus yeemveliso ze-FRP. Ukusebenza kweemveliso ze-pultruded usebenzisa izinto ezahlukeneyo zokuqinisa nazo zihluke.

Ukongeza, ngelixa uhlangabezana neemfuno zokusebenza kwemveliso yenkqubo yokubumba, iindleko kufuneka ziqwalaselwe, kwaye izixhobo zokuqinisa ezixabiso eliphantsi kufuneka zikhethwe kangangoko kunokwenzeka. Ngokubanzi, ukuzulazula okungakhethiyo kwemisonto yefiber yeglasi kunexabiso eliphantsi kunamalaphu efayibha; iindleko zeiimathi zefiber zeglasiingaphantsi kunelaphu, kwaye ukunganyanzeki kulungile. , kodwa amandla aphantsi; ifayibha yealkali inexabiso eliphantsi kune-alkali-free fiber, kodwa ngokunyuka komxholo wealkali, ukuxhathisa kwayo kwealkali, ukumelana nokubola, kunye neempawu zombane ziya kuncipha.

Iindidi zezixhobo ezisetyenziswa ngokuqhelekileyo zokuqinisa zilandelayo

1. I-fiber yeglasi engajikwanga

Ukusebenzisa i-ejenti yokulinganisa eyomeleziweyo, engajikwangai-fiber yeglasi yokujikelezainokohlulwa ibe ziindidi ezintathu: isilika ekrwada yeplied, i-roving ethe ngqo engasontiyo kunye ne-bulked untwisted roving.

Ngenxa yoxinzelelo olungalinganiyo lwemicu yeplied, kulula ukuntywila, okwenza i-loop evulekileyo ekupheleni kokutya kwezixhobo ze-pultrusion, echaphazela inkqubela phambili yokusebenza.

Ukuzulazula okuthe ngqo okungajikwanga kuneempawu zokudityaniswa kakuhle, ukungena kwe-resin ngokukhawuleza, kunye neempawu ezigqwesileyo zomatshini weemveliso, ngoko ke uninzi lweerovings ezithe ngqo ezingajijekanga zidla ngokusetyenziswa ngoku.

I-rovings ene-bulked rovings iluncedo ekuphuculeni ukomelela okunqamlezayo kweemveliso, ezinje nge-crimped rovings kunye ne-air-textured rovings. I-Bulk roving inamandla aphezulu eentsinga ezinde eziqhubekayo kunye nobuninzi beentsinga ezimfutshane. Yimpahla enokumelana nobushushu obuphezulu, i-conductivity ephantsi ye-thermal, i-corrosion resistance, umthamo ophezulu kunye nokusebenza kakuhle kokucoca. Ezinye iintsinga zixutywe kwimo ye-monofilament, ngoko inokuphucula umgangatho wemveliso ye-pultruded. Okwangoku, i-rovings bulked isetyenziswe ngokubanzi ekhaya nakwamanye amazwe, njengeentambo ezirp kunye ne-weft zokuhombisa okanye kwimizi-mveliso elukiweyo. Ingasetyenziselwa ukuvelisa ukukhuhlana, ukugquma, ukukhuselwa okanye izinto zokutywina.

Iimfuno zokusebenza zeglasi engajikwanga yefiber rovings yepultrusion:

(1) Akukho siganeko sijijekileyo;

(2) I-fiber tension ifana;

(3) Ukudibanisa kakuhle;

(4) Ukumelana nokunxiba kakuhle;

(5) Kukho iintloko ezimbalwa ezaphukileyo, kwaye akulula ukuzigungxula;

(6) Ukumanzisa okulungileyo kunye nokufakwa ngokukhawuleza kwe-resin;

(7) Amandla aphezulu kunye nokuqina.

2. I-glass fiber mat

Ukuze wenze iimveliso ze-FRP eziphothiweyo zibe namandla okwaneleyo anqamlezileyo, izixhobo zokuqinisa ezifana ne-strand mat enqunqiweyo, i-continuous strand mat, i-mat edibeneyo, kunye nelaphu elingasontiyo kufuneka lisetyenziswe. I-continuous strand mat yenye yezona zinto zixhaphakileyo zisetyenziswa kwigilasi fiber transverse ukuqinisa imathiriyeli ngoku. Ukuze kuphuculwe inkangeleko yeemveliso,umphezulu matngamanye amaxesha isetyenziswa.

I-strand mat eqhubekayo yenziwe ngamacandelo amaninzi eentsinga zeglasi eziqhubekayo ezibekwe ngokungacwangciswanga kwisangqa, kwaye iifiber ziboshwe kunye ne-adhesives. Umphezulu uvakale ngathi liphepha elicekethekileyo elivakala njengephepha elenziwe ngokungacwangciswanga nangokulinganayo ngokubeka imicu enqunqiweyo yobude obusisigxina kwaye idityaniswe ngento encamathelayo. Umxholo wefiber ngu-5% ukuya kwi-15%, kwaye ubukhulu be-0.3 ukuya kwi-0.4 mm. Inokwenza ubuso bemveliso bugudiswe kwaye bubuhle, kwaye buphucule ukumelana nokuguga kwemveliso.

Iimpawu zeglasi ye-fiber mat zezi: ukugubungela kakuhle, kulula ukuhluthwa nge-resin, umxholo weglue ophezulu

Iimfuno zenkqubo ye-pultrusion ye-glass fiber mat:

(1) Unamandla omatshini aphezulu

(2) Kwiimethi zomsonto odityanisiweyo wekhemikhali, isibophelelo kufuneka sixhathise kwimichiza kunye neziphumo ze-thermal ngexesha lokudipha kunye nokulungiswa kwangaphambili ukuqinisekisa ukomelela okwaneleyo ngexesha lenkqubo yokwenza;

(3) Ukumanzisa okulungileyo;

(4) I-fluff encinci kunye neentloko ezimbalwa ezaphukileyo.

3. I-polyester fiber surface mat

Umphezulu wefiber yepolyester uvakele luhlobo olutsha lwemathiriyeli yokuqinisa ifayibha kwishishini le-pultrusion. Kukho imveliso ebizwa ngokuba yi-Nexus e-United States, esetyenziswa ngokubanzi kwiimveliso ze-pultruded ukubuyiselaiimethi zeglasi zefibre. Inesiphumo esihle kunye neendleko eziphantsi. Isetyenziswe ngempumelelo iminyaka engaphezu kwe-10.

Iinzuzo zokusebenzisa i-polyester fiber tissue mat:

(1) Inokuphucula ukuxhathisa impembelelo, ukuxhathisa ukubola kunye nokumelana nokuguga kwe-atmospheric yeemveliso;

(2) Iyakwazi ukuphucula umgangatho wemveliso kwaye yenza ubuso bemveliso bube lula;

3

(4) Isantya se-pultrusion sinokunyuswa;

(5) Inokunciphisa ukunxiba kwesikhunta kunye nokuphucula ubomi benkonzo yobumba

4. Itheyiphu yelaphu lelaphu leglasi

Kwezinye iimveliso ezikhethekileyo ze-pultruded, ukuze kuhlangatyezwane neemfuno ezikhethekileyo zokusebenza, ilaphu leglasi elinobubanzi obumiselweyo kunye nobukhulu obungaphantsi kwe-0.2mm liyasetyenziswa, kwaye amandla alo okuqina kunye namandla anqamlezayo alungile kakhulu.

5. Ukusetyenziswa kwamalaphu amacandelo amabini kunye neendwangu ezintathu-dimensional

Iimpawu ezinqamlezayo zomatshini wemveliso ye-pultruded composite ihlwempuzekileyo, kwaye ukusetyenziswa kwe-bidirectional braiding kuphucula ngokufanelekileyo amandla kunye nokuqina kweemveliso ezixutywe.

Iintsinga ze-warp kunye ne-weft yeli laphu elilukiweyo ayidityaniswanga enye kwenye, kodwa idityaniswe nenye into elukiweyo, ngoko ke yahluke ngokupheleleyo kwilaphu leglasi yemveli. Iifiber kwicala ngalinye zikwimeko edibeneyo kwaye azenzi Nakuphi na ukugoba, kwaye ngoko ke amandla kunye nokuqina kwemveliso ye-pultruded, iphezulu kakhulu kunokuba i-composite eyenziwe ngokuziva ngokuqhubekayo.

Okwangoku, itekhnoloji yendlela-ntathu yokuluka iye yaba yeyona ndawo inomtsalane kunye nesebenzayo yophuhliso lwetekhnoloji kushishino lwezinto ezihlanganisiweyo. Ngokweemfuno zomthwalo, i-fiber yokuqinisa ilukwe ngokuthe ngqo kwisakhiwo esinesakhiwo esine-dimensional ezintathu, kwaye imilo iyafana naleyo yemveliso edibeneyo eyenza. Ilaphu elineendlela ezintathu lisetyenziswa kwinkqubo ye-pultrusion ukoyisa i-interlaminar shear yeemveliso zemveli zokuqinisa ifayibha pultrusion. Inobugwenxa bamandla okucheba asezantsi kunye ne-delamination elula, kwaye ukusebenza kwayo kwe-interlayer ilungile.
