Puas yog polyurethane ua npuas dej muaj cov fiberglass?
Polyurethane ua npuas ncauj tsis muaj fiberglass li ib feem ntawm nws muaj pes tsawg leeg. Txawm li cas los xij, ob cov ntaub ntawv qee zaum siv ua ke rau qee cov ntawv thov, ua rau tsis meej pem. Cia peb ua txhaum txoj kev sib raug zoo los qhia meej txog kev sib raug zoo ntawm Polyurethane ua npuas ncauj thiab fiberglass.
Dab tsi yog polyurethane ua npuas ncauj?
Polyurethane ua npuas ncauj yog ib cov khoom siv ntau yam tsim los ntawm kev rov qab polyols (sib xyaw ua ke) nrog Isocyanates. Nws los hauv ob hom loj:
Qhib-cell ua npuas ncauj:Mos thiab yoog tau, feem ntau siv hauv Cushions, daim txaj txaj, thiab soundproofing.
-Cell Ua Npuas Ncauj:Rigid thiab ntom, kheev siv nyob rau hauv rwb thaiv tsev thiab waterproofing.
Cov iav fiberglass, ntawm qhov tod tes, yog tsim los ntawm cov iav zoo nkauj thiab feem ntau yog siv los ua cov khoom siv lossis rwb thaiv tsev.
Puas yog polyurethane ua npuas dej muaj cov fiberglass?
Polyurethane ua npuas ncauj, los ntawm nws tus kheej, tsis suav cov fiberglass hauv nws cov tshuaj pleev. Txawm li cas los xij, ob yam khoom siv feem ntau siv nyob rau hauv tandem rau cov hom phiaj tshwj xeeb. Ntawm no yog li cas:
1. Fiberglass-txhawb nqa polyurethane ua npuas ncauj
Lub hom phiaj:Muaj qee kis, fiberglass tau ntxiv rau polyurethane ua npuas ncauj kom txhim kho nws cov kev muaj zog thiab lub zog. Qhov no yog ib txwm muaj nyob rau hauv kev tsim kho thiab muaj kev lag luam uas cov neeg ua npuas ncauj xav tau kev txhawb ntxiv.
Piv txwv:Kev siv hluav taws xob, mould rau txhua qhov rau kev siv tsheb lossis kev siv roj av, thiab qee yam ntawm cov laug cam txhav.
2. Polyurethane ua npuas ncauj siv nrog rwb thaiv tsev fiberglass
Lub hom phiaj:POLYURETHANE ua npuas ncauj qee zaum yog tshuaj tsuag hla cov txheej txheem fiberglass uas sib xyaw ua ke ntawm cov thiberglass nrog cov cua-sealing cov khoom ntawm ua npuas ncauj.
Cov Ntawv Thov:Qhov kev sib xyaw no tau nrov hauv kev ua haujlwm hauv tsev, qhov uas nws txhim kho lub zog hluav taws xob thiab txo cov cua to.
3. Cov ntaub ntawv fiberglass ua cov khoom siv rov qab
Lub hom phiaj:Qee cov khoom lag luam polyurethane ua npuas dej, xws li npuas panels lossis upholstery, tej zaum yuav muaj lub zog rov qab rau kev siv lub zog lossis hluav taws kub tiv thaiv.
Piv txwv:Automotive interiors, rooj tog zaum, thiab vaj huam sib luag.
Kev Noj Qab Haus Huv thiab Kev Txiav Txim Kev Nyab Xeeb
Thaum patyurethane ua npuas ncauj nws tus kheej tsis ua rau muaj kev pheej hmoo ntsig txog fiberglass, siv ob cov ntaub ntawv ua ke tej zaum yuav qhia qee yam kev txhawj xeeb:
Cov kev pheej hmoo fiberglass
Voos:Cov ntsuas cov fiberglass tuaj yeem ua rau tawv nqaij, ob lub qhov muag, thiab ua pa yog tias lawv tau ua pa thaum lub teeb lossis tuav.
Inhalation:Ntev kom raug rau cov hmoov av fiberglass yuav ua rau muaj kev ua pa.
Polyurethane ua npuas ncauj kev phom sij
Off-gassing:Fresh Polyurethane ua npuas dej tuaj yeem ua emit volatile cov organic cov tebchaw (VOCS), uas tuaj yeem ua rau muaj kev txob txob ib ntus lossis tsw qab.
Flammability:Yog tsis muaj cov tshuaj ntxiv tsim nyog, polyurethane ua npuas dej tuaj yeem ua rau muaj ntsej muag, txawm tias qhov kev pheej hmoo no raug txiav los ntawm kev ntxiv cov nplaim hluav taws.
Yuav ua li cas txheeb tau yog fiberglass yog tam sim no
Yog tias koj tsis paub meej tias cov khoom lag luam polyurethane ua npuas dej muaj cov fiberglass, xav txog cov hauv qab no:
Cov Ntawv Cim:Txheeb xyuas cov ntsiab lus ntawm cov fiberglass txhawb lossis rov qab.
Chaw tsim tshuaj paus:Saib cov ntaub ntawv cov ntaub ntawv txheej txheem lossis ntawv pov thawj uas nthuav cov ntaub ntawv siv.
Kev Ntsuam Xyuas Pom:Fiberglass feem ntau tshwm raws li cov ntaub ntawv woven lossis fibrous txheej, txawv los ntawm kev ntxhib los mos ntawm ua npuas ncauj.
