SWKS yog tus muab kev pabcuam txhaj tshuaj moulded polyurethane qhov chaw thiab cov khoom siv. Peb muaj ntau dua 20 xyoo kev paub thiab cov ntaub ntawv paub zoo uas pab peb tsim cov khoom lag luam zoo, muaj qhov tseeb uas haum rau peb cov neeg siv khoom tsim tshwj xeeb. Peb tswj hwm kev nruj thiab tuaj yeem tsim txawm tias qhov nyuaj tshaj plaws nrog qhov tshwj xeeb zoo ib yam thiab rov ua dua.
Tiv tauj peb kom paub ntau ntxiv txog peb qhov kev txhaj tshuaj PU kev xaiv rau kev txhim kho cov khoom hnav thiab ua haujlwm ntev thiab peb yuav zoo siab pab koj nrog koj cov lus tshwj xeeb polyurethane txhaj tshuaj molding.
Polyurethane Txhaj Tshuaj Molding Txheej Txheem
Txhaj tshuaj molding yog txheej txheem rov ua dua nrog lub sijhawm hloov pauv nrawm heev uas tshwm sim hauv ib qho tshwj xeeb, siv lub tshuab txhaj tshuaj molding. Cov txheej txheem txhaj tshuaj PU muaj cov hauv qab no:
Cov khoom siv polyurethane tau ncaj qha pub rau hauv lub tshuab txhaj tshuaj.
Lub thoob cov ntsia hlau sib tsoo thawb cov polyurethane pellets mus rau pwm.
Kev txiav siab ua haujlwm ntawm cov ntsia hlau sib txhuam ua kom sov cov pellets, ua kom lawv yaj tag thaum kawg ntawm lub thoob.
Thaum cov khoom txaus tau sau ntawm qhov kawg ntawm lub thoob, cov polyurethane uas tau yaj tau raug yuam kom siab thiab nrawm rau hauv cov pwm hauv ib qho txhaj tshuaj.
Cov khoom nkag mus rau hauv pwm los ntawm kev sib txuas ntawm cov rooj vag.
Thaum cov khoom tau khov kho, pwm tau qhib, thiab cov khoom raug tshem tawm siv cov koob ntawm lub ntsej muag, lub tes tsho, thiab cov hleb.
PU Txhaj Tshuaj Molding Specifications
Polyurethane muaj kev tiv taus zoo heev - txawm tias nyuaj tshaj polyurethanes tuaj yeem tsim rau qhov rov ua kom muaj txiaj ntsig txog li 70%. Cov khoom siv thermoplastic no muaj cov khoom tiv thaiv zoo heev, me me kom tsis muaj dej nqus, thiab tiv taus cov roj, roj, tshuaj lom neeg, thiab hluav taws xob. Polyurethanes tuaj yeem tsim kom tiv taus siv tas li ntawm qhov kub siab txog 248 ° F (120 ° C).
Ntawm SWKS, peb tuaj yeem muab cov copolymer tshwj xeeb uas sib xyaw polyurethane thiab ib lossis ntau dua lwm yam khoom siv yas thiab sib txuas lawv cov yam ntxwv rau kev ua tau zoo dua, ua haujlwm ntev, thiab lwm yam.
Qhov zoo ntawm Polyurethane Thermoplastic Txhaj Tshuaj Molding
PU txhaj tshuaj molding tsim cov khoom thiab cov khoom uas muaj ntau yam, niaj hnub thiab nyab xeeb. Lawv tau siv hauv ntau daim ntawv thov los tsim ntau yam khoom lag luam uas nkag tau yooj yim, nyab xeeb thiab nyiam ib puag ncig. Qee qhov txiaj ntsig ncaj qha los ntawm kev siv txhaj tshuaj molding polyurethane hauv kev tsim cov khoom thiab cov khoom suav nrog:
Lub teeb yuag qauv
Muaj zog& ruaj
Qhov cuam tshuam tiv taus
Lub peev xwm ua tau zoo
Puas& hnav tiv taus
Khaws cov duab ntawm qhov siab thiab qis kub
Tshuaj tiv taus
Txhaj Tshuaj Molding Polyurethane Daim Ntawv Thov
Thaum siv nyob rau hauv kev txhaj tshuaj txheej txheem, cov khoom siv polyurethane thermoplastic tuaj yeem tsim kho kom haum raws li qhov tshwj xeeb xav tau ntawm txoj haujlwm. Qee qhov kev siv ntau uas tuaj yeem tsim los ntawm cov txheej txheem txhaj tshuaj polyurethane suav nrog:
Cov tsheb
Cov nplaum
Lub tsev tsim khoom
Rwb thaiv tsev
Cov vaj huam sib luag
Cov khoom siv ncaws pob
Qhov sib txawv ntawm Thermoplastic Polyurethane (TPU)& Rigid Thermoplastic Polyurethane (RTPU)
Thermoplastic polyurethane (TPU) yog elastomer uas yog ywj thiab yaj-txheej txheem. Nws kuj tseem tuaj yeem ua tiav ntawm extrusion ntxiv rau kev txhaj tshuaj, tshuab thiab tshuab molding cov cuab yeej. TPU muab ntau yam khoom siv hauv lub cev ua ke ua rau nws cov khoom hloov pauv tau yooj yim hloov pauv tau rau ntau qhov kev siv. TPU tswj hwm ntau yam zoo heev suav nrog kev nthuav tawm siab, nce lub zog tensile thiab zoo elasticity.
Hloov pauv, cov thermoplastic polyurethane txhav (RTPU) yog cov thermoplastic engineering uas yuav tuaj pwm kom nruj rau qhov ntev tsis muaj kev puas tsuaj. Nws cov tshuaj tiv thaiv zoo ib yam li cov khoom siv ib nrab crystalline, muab tshuaj lom neeg ua haujlwm tsis zoo, ua haujlwm tau zoo thiab muaj zog cuam tshuam.
