PU yog lub npe luv ntawm polyurethane hauv lus Askiv, thiab lub npe tshuaj hauv Suav yog "polyurethane". PU tawv yog daim tawv nqaij ua los ntawm polyurethane. Nws yog dav siv hauv kev kho kom zoo nkauj ntawm lub hnab, khaub ncaws, khau, tsheb thiab rooj tog. Nws tau raug lees paub los ntawm kev ua lag luam. Nws cov kev siv ntau yam, ntau qhov ntau thiab ntau yam tsis tuaj yeem txaus siab los ntawm cov tawv nqaij tawv. Qhov zoo ntawm PU tawv kuj txawv, thiab cov tawv PU zoo tseem zoo dua li tawv tiag.
Hauv Suav teb, tib neeg tau siv los hu cov tawv tawv uas ua nrog PU cob ua raw khoom PU tawv tawv (PU tawv luv luv); Cov tawv tawv uas ua nrog PU resin thiab cov ntaub tsis-woven li raw cov ntaub ntawv hu ua PU hluavtaws tawv (synthetic tawv luv). Nws yog kev cai los sib sau ua ke rau saum peb hom tawv li hluavtaws tawv.
Artificial tawv thiab hluavtaws tawv yog ib feem tseem ceeb ntawm kev lag luam plastics thiab tau dav siv nyob rau hauv ntau yam lag luam ntawm lub teb chaws kev lag luam. Kev tsim cov tawv tawv thiab hluavtaws tawv muaj keeb kwm ntawm ntau tshaj 60 xyoo ntawm kev loj hlob hauv ntiaj teb. Tuam Tshoj tau pib tsim thiab tsim cov tawv tawv hauv xyoo 1958. Nws yog ib qho kev lag luam uas tsim ua ntej hauv Tuam Tshoj txoj kev lag luam yas. Txoj kev loj hlob ntawm Tuam Tshoj cov tawv tawv thiab hluavtaws tawv kev lag luam tsis yog tsuas yog kev loj hlob ntawm cov khoom siv ntau lawm kab ntawm cov tuam txhab tsim khoom, cov khoom tsim tawm tau nce xyoo los ntawm lub xyoo, thiab ntau yam thiab xim nce xyoo los ntawm lub xyoo, tab sis kuj muaj cov txheej txheem kev lag luam muaj nws lub koom haum kev lag luam. , uas muaj kev sib koom ua ke ntau heev, kom Tuam Tshoj cov tawv tawv tuaj yeem ua tau, cov tuam txhab tawv hluavtaws, nrog rau cov kev lag luam muaj feem xyuam, tau koom ua ke thiab tsim rau hauv kev lag luam nrog lub zog loj.
Ua raws li PVC tawv tawv, PU hluavtaws tawv tau ua tiav cov txheej txheem thev naus laus zis los ua ib qho zoo tagnrho hloov rau cov tawv nqaij tom qab ntau tshaj 30 xyoo ntawm kev tshawb fawb thiab kev loj hlob los ntawm kev tshawb fawb thiab thev naus laus zis.
PU txheej rau saum npoo ntawm cov ntaub thawj zaug tau tshwm sim hauv khw hauv xyoo 1950. Xyoo 1964, American DuPont Company tau tsim PU hluavtaws tawv rau khau khau. Tom qab lub tuam txhab Nyij Pooj tau tsim cov kab ntau lawm nrog cov khoom tsim tawm txhua xyoo ntawm 600,000 square metres, tom qab ntau tshaj 20 xyoo ntawm kev tshawb fawb thiab kev loj hlob, PU hluavtaws tawv tau loj hlob sai ntawm cov khoom zoo, ntau yam, thiab cov khoom tsim tawm. Nws qhov kev ua tau zoo tau los ze zog thiab ze rau cov tawv nqaij, thiab qee cov khoom tseem ceeb tshaj li cov tawv nqaij, mus txog qhov uas nws nyuaj rau kev paub qhov txawv ntawm cov tawv tiag tiag thiab cov tawv nqaij cuav. Nws tuav txoj haujlwm tseem ceeb heev hauv tib neeg lub neej txhua hnub.
Niaj hnub no, Nyiv yog cov neeg tsim khoom loj tshaj plaws ntawm cov tawv hluavtaws. Cov khoom ntawm Kuraray, Teijin, Toray, Zhongbo thiab lwm lub tuam txhab pib sawv cev rau theem thoob ntiaj teb kev loj hlob nyob rau xyoo 1990s. Nws cov fiber ntau thiab tsis-woven npuag raug tsim nyob rau hauv kev coj ntawm ultra-nplua, high-density thiab siab tsis-woven los; nws cov PU manufacturing yog tsim nyob rau hauv cov kev taw qhia ntawm PU dispersion thiab PU dej emulsion, thiab nws cov khoom daim ntawv thov teb yog tas li nthuav, pib los ntawm nkawm khau thiab hnab . npog txhua yam ntawm tib neeg lub neej txhua hnub.
Artificial tawv yog qhov ntxov tshaj plaws hloov rau tawv fabrics invented. Nws yog tsim los ntawm PVC ntxiv rau cov yas yas thiab lwm yam khoom siv ntxiv, calendered thiab compounded ntawm daim ntaub. Qhov zoo yog pheej yig, nplua nuj xim thiab ntau yam qauv. Qhov tsis zoo yog tias nws hardens yooj yim thiab Ua brittle. PU hluavtaws tawv yog siv los hloov PVC tawv tawv, thiab nws tus nqi siab dua PVC tawv tawv. Hais txog cov qauv tshuaj, nws yog ze rau cov ntaub npuag tawv. Nws tsis siv plasticizers kom ua tiav cov khoom muag, yog li nws yuav tsis ua tawv lossis nkig. Nws kuj muaj qhov zoo ntawm cov xim nplua nuj thiab ntau yam qauv, thiab yog pheej yig dua li tawv fabrics. Yog li nws tau txais tos los ntawm cov neeg siv khoom.
Kuj tseem muaj PU nrog tawv. Feem ntau, sab nraub qaum yog txheej thib ob ntawm cowhide, thiab txheej txheej ntawm PU resin yog coated rau saum npoo, yog li nws tseem hu ua zaj duab xis cowhide. Nws tus nqi pheej yig dua thiab nws cov nqi siv yog siab. Nrog rau cov kev hloov hauv kev siv tshuab, nws kuj tau ua rau ntau qib, xws li imported ob-txheej cowhide. Vim nws cov thev naus laus zis tshwj xeeb, ruaj khov zoo, thiab ntau yam tshiab, nws yog tawv tawv, thiab nws cov nqi thiab qib tsis tsawg dua li thawj-txheej tawv tawv. PU tawv hnab thiab cov hnab tawv tiag tiag muaj lawv tus kheej yam ntxwv. PU tawv hnab muaj qhov zoo nkauj zoo nkauj, saib xyuas yooj yim, thiab pheej yig, tab sis tsis hnav-tiv taus thiab yooj yim tawg. Cov hnab tawv tiag tiag yog kim thiab teeb meem rau kev saib xyuas, tab sis lawv ruaj khov.
Muaj ob txoj hauv kev kom paub qhov txawv ntawm cov tawv nqaij los ntawm PVC tawv tawv thiab PU hluavtaws tawv: ib qho yog qhov softness thiab hardness ntawm tawv, tawv tiag tiag yog mos thiab PU yog tawv, yog li PU feem ntau yog siv hauv khau tawv; lwm qhov yog siv qhov kub thiab melting Txoj kev kom paub qhov txawv yog muab ib daim ntaub me me thiab muab tso rau hauv qhov hluav taws kub. Tawv ntaub yuav tsis yaj, tab sis PVC tawv tawv thiab PU hluavtaws tawv yuav yaj.
Qhov sib txawv ntawm PVC tawv tawv thiab PU hluavtaws tawv tuaj yeem paub qhov txawv los ntawm kev ntub nws hauv roj av. Txoj kev yog siv ib daim ntaub me me, muab tso rau hauv roj av rau ib nrab teev, thiab tom qab ntawd muab nws tawm. Yog tias nws yog PVC tawv tawv, nws yuav nyuaj thiab nkig. PU hluavtaws tawv yuav tsis ua tawv lossis tawv.
