Vim nws muaj pes tsawg leeg muaj zog, pom kev ntom ntom thiab tib lub sijhawm muaj kev ywj pheej, fiberglass tau txais lwm lub npe - "lub teeb hlau". Nws yog cov khoom siv nrov uas tau siv hauv txhua qhov kev lag luam uas muaj nyob.
Kev piav qhia thiab qhov dav
Fiberglass yog cov ntawv sib xyaw ua ke nrog lub zog ntawm cov hlau thiab muaj peev xwm los ua cua sov nyob hauv cov ntoo ntuj. Nws muaj pes tsawg leeg suav nrog cov khoom sib txuas - polyester, polycondensation compound thiab muab tub lim, uas yog siv los ua cov khoom siv rov ua dua tshiab (cullet).
Nyob ntawm tus muab tub lim - iav fibers, cov khoom yog du, ntxiv rau ntxhib los yog nplua nthwv dej. Cov ntawv fiberglass muaj cov yam ntxwv tseem ceeb ntawm lub cev thiab tshuaj, uas yog qhov txiav txim siab rau nws txoj haujlwm:
- qhov ua kom pom tseeb - cov khoom muaj qhov nqus tshwj xeeb tsawg;
- siab txhua yam zog;
- xim tsis txwv;
- muaj peev xwm tawg teeb;
- tsis muaj dej - cov tshuaj muaj pes tsawg leeg tsis nqus dej;
- tiv taus xeb, rot, kab mob, organic decomposition, deformation;
- qhov kub thiab txias ntau yam (ntawm -50 txog +50 degrees), uas nws tuaj yeem siv tau yam tsis ntshai kev ua txhaum ntawm cov khoom muaj txiaj ntsig thiab kev puas tsuaj;
- cov ntawv fiberglass tsis raug rau qhov tsis zoo ntawm tshav ntuj thiab hlawv;
- tsis muaj qhov ntxim nyiam rau cov tshuaj hnyav, suav nrog ntsev, alkalis thiab kua qaub;
- zoo dielectric zoo;
- lub peev xwm ntawm cov khoom siv los tu tus kheej;
- tiv taus lub cev kev nyuaj siab, tsis muaj kev puas tsuaj xws li daim tawv nqaij;
- cov txheej txheem monolithic ntawm cov ntawv ua rau nws muaj peev xwm khaws cov xim zas xim, yog li ntawd, nws muaj peev xwm thov siv cov khoom dai ntawm cov khoom siv fiberglass.
Qhov tsis zoo ntawm daim ntawv fiberglass tau suav tias yog poob lub zog thaum lub sijhawm ua haujlwm, kev hloov pauv thaum khoov vim tsis muaj kev ywj pheej, tsis muaj kev cuam tshuam los ntawm kev txhuam hniav, txo qis zog, tsim cov hmoov av tsis zoo thaum ua. Rau ntau hom khoom lag luam uas tau npaj yuav ua los ntawm fiberglass, ntau yam khoom ntim tau siv - cov nets woven, canvases, mats thiab kab xev, pob khoom, hlua thiab lwm yam khoom sib tw.
Kev siv cov ntaub ntawv no:
- Kev lag luam tsheb;
- tsim cov ntu rau cov khoom siv hluav taws xob;
- tsim cov cuab yeej hluav taws xob thiab khoom siv;
- kev tsim kho nkoj, dav hlau, chaw thev naus laus zis;
- hauv kev lag luam roj thiab roj, SPMs tau siv rau kev tsim cov tso tsheb hlau luam, tso tsheb hlau luam, thiab lwm yam ntim rau khaws cia thiab thauj cov khoom no.
Dhau li, fiberglass daim ntawv yog cov khoom siv nrov rau rwb thaiv tsev ntawm cov vans, tsim cov tso tsheb hlau luam tshwj xeeb uas thauj zaub mov … Vim tias lawv cov cua sov tsis zoo, SPMs feem ntau siv rau kev rwb thaiv tsev cua sov hauv kev tsim kho kev lag luam. Cov khoom siv yog xav tau hauv kev tsim cov khoom lag luam sab nraum zoov, khoom siv hauv tsev, khoom sab hauv.
Txawm li cas los xij, cov khoom siv no tshwj xeeb tshaj yog tsim rau ntau yam khoom siv hauv tsev, xws li microwave ncu, tshuab ntxhua khaub ncaws, phiab, vase, khoom ua si, khoom siv tes ua, rooj zaum, ntawv sau.
Saib
Cov ntawv fiberglass tau tsim tawm hauv 3 lub hlis
- Nyob rau hauv daim ntawv ntawm fibroton Yog pob tshab, cov khoom siv tinted uas feem ntau siv rau lub hom phiaj zoo nkauj, vim nws muaj nyob hauv cov xim dav.
- Nyob rau hauv daim ntawv ntawm fiber ntau rover siv rau cladding thiab ru tsev . Nws yog fiberglass-reinforced polyester ua hauv cov xim sib txawv thiab sib txawv los ntawm lwm hom SPM hauv qhov uas nws tsis pom kev.
- Fibrolight muaj qhov pom tseeb , uas xa lub teeb los ntawm 92%, uas yog, yuav luag tsis qis dua iav zoo tib yam. Nws tau siv los ua qhov chaw ntsiag to, cov vaj huam sib luag tshwj xeeb rau nruab hnub nrig, chav dai khaub ncaws thiab lub ru tsev kom tso lub teeb pom kev zoo nkag mus rau hauv chav, tsis yog lwm yam khoom siv kim. Tab sis, tau kawg, feem ntau siv fibrolite los tsim lub tsev cog khoom thiab tsev cog khoom, vim nws tsis cuam tshuam los ntawm cov kab mob nyob.
Ua ke nrog cov hom fiberglass, nws yog rau lub hom phiaj hauv tsev uas siv cov ntawv sib xyaw ua ke nrog cov tuab ntawm 0.8 txog 2 hli feem ntau siv. Qhov ntev ntawm cov khoom lag luam no tuaj yeem sib txawv ntawm 1000 txog 6000 mm.
Cov ntaub ntawv no yog ob qho tib si thoob ntiaj teb thiab npaj tshwj xeeb rau kev tsim cov laj kab thiab lub ru tsev.
Nta ntawm kev ua haujlwm
Ua haujlwm nrog fiberglass cuam tshuam nrog kev txiav nws, thiab qhov no xav tau kev paub txog kev ua haujlwm thiab muaj cov cuab yeej tsim nyog
- Kev txiav tes yuav xav tau kev siv cuab yeej xws li hacksaw rau hlau. Qhov kev xaiv no yog qhov tsim nyog yog tias koj xav tau txheej txheem cov ntawv fiberglass me me nrog cov tuab tsis ntau tshaj 2 hli. Tab sis qhov no ua rau muaj hmoov av ntau, thiab qhov no yog qhov tsis zoo ntawm txoj hauv kev.
- Rau kev ua cov ntaub ntawv nyias, cov cuab yeej siv tshuab yog qhov tsim nyog - rab riam los yog rab riam. Tus nqi pheej yig tshaj plaws thiab yooj yim txiav cov cuab yeej yog riam riam. Koj kuj tseem yuav xav tau tus thawj coj - thaum xub thawj, ob peb kab rov tav tau ua nrog nws, tom qab ntawd cov ntu uas xav tau yuav tsum tau tawg nrog cov pliers. Kev ua tiav ntxiv muaj nyob hauv kev txhuam cov npoo nrog txhuam los yog nplua-nplua emery.
- Yog tias koj xav tau txiav cov ntawv loj, nws yog qhov zoo dua los siv cov hniav pom nrog peb lub hniav, uas muaj peev xwm kov yeej cov khoom tau txog li 10 hli tuab.
- Fiberglass los xij ntawm cov loj loj 2000 los ntawm 1220 mm nrog tuab 5 mm tuaj yeem txiav sai sai siv lub tshuab zom, lub zom zom lossis lub tshuab saw tshwj xeeb.
Qhov cuab yeej siv twg los xij, tsis txhob hnov qab tias thaum ua haujlwm nrog cov khoom siv no nws yog ib qho tseem ceeb kom soj ntsuam kev nyab xeeb thiab nco ntsoov tiv thaiv lub ntsej muag thiab lub cev ua pa nrog lub npog ntsej muag, thiab lub qhov muag nrog tsom iav. Nws raug nquahu kom tiv thaiv koj txhais tes nrog cov yas yas lossis hnab looj tes silicone.
