Ib qho ntawm cov ntaub ntawv tseem ceeb ntawm polyurethane txheej yog polyurethane tawv ua npuas ua ke polyether. Polyurethane ua npuas dej ua ke polyether tseem hu ua cov khoom dawb, thiab polymerization MDI hu ua cov khoom dub thiab dawb. Nws yog qhov tsim nyog rau kev tsim tsev rwb thaiv tsev, tiv thaiv khaub thuas, hnub ci zog, rhaub dej, txias txias, khaws cia qhov kub thiab txias, npias npias, txias txias thiab lwm yam.
Yim yam kev tsim kho ntawm polyurethane txheej:
1. Tasteless, zwm rau ib puag ncig tiv thaiv cov khoom lag luam, kev tsim kho yooj yim, daim ntawv thov dav, tsim nyog rau kev tsim kho tsis muaj dej thiab cov khoom hauv tsev nyuaj.
2. Polyurethane txheej tuaj yeem tsim cov roj hmab tsis tu ncua zoo li, ua tiav cov txheej txheej tsis muaj dej tsis qab tom qab kho. Cov dej tsis muaj peev xwm thiab tsis muaj peev xwm ua tau ntawm lub tsev tsim vaj tsev yog dhau qhov ncav cuag cov khoom lag luam.
3. Cov zaj duab xis txheej ntawm polyurethane txheej muaj lub zog siab thiab nthuav dav, uas tsim nyog rau kev tawg lossis nthuav dav ntawm lub hauv paus.
4. Ua kom txias txias, kev tsim kho tsis cuam tshuam los ntawm qhov ntsuas kub, txoj kev tsim kho tuaj yeem siv tshuaj tsuag, txhuam, khawb, dov thiab lwm txoj hauv kev, kev tsim kho yog yooj yim, yooj yim kho.
5. Kev saib xyuas yooj yim, tsuas yog ua rau cov khoom puas ntawm kev saib xyuas hauv zos, tseem tuaj yeem ua tiav thawj qhov dej tsis huv.
6. Muaj peev xwm xa tawm ntawm cov xim qaim, tuaj yeem ua lub luag haujlwm ua kom zoo nkauj zoo nkauj, ua los ntawm cov khoom lag luam pob tshab.
7. Cov txheej txheej polyurethane yuav tsum tau qib, tsis yog xuab zeb, thiab kev nyuaj siab yog qib nrog tshuaj khib.
8. Polyurethane txheej muaj cov yam ntxwv ntawm acid, alkali, nplaim hluav taws, rwb thaiv tsev, tiv thaiv kev laus thiab lwm yam.
Polyurethane txheej cov khoom no yog pawg tseem ceeb ntawm peb cov kev tshawb fawb thiab kev txhim kho, yog li txawm hais tias ntau yam no tuaj yeem ua lub luag haujlwm zoo hauv daim ntawv thov, rau nws tus kheej, nws kuj muaj qhov zoo thiab qhov tsis zoo, tsis yog txhua yam ntawm cov khoom no zoo, lossis yog, hauv chav kawm, hauv lawv cov lus zoo sib xws, kev tshuaj xyuas ntawm polyurethane txheej. Muaj ntau hom kev khaws cia ntawm ammonia ester txheej log, yog li niaj hnub no peb txheej polyurethane, los qhia koj yog ib txoj hauv kev khaws cia kom raug, txoj hauv kev no muaj txiaj ntsig zoo hauv ib txwm muaj xwm txheej, vim nws yog txoj hauv kev yooj yim. Nws' kuj yog txoj hauv kev yooj yim rau peb khaws.
Tom qab siv lub hnab yas polyurethane thaum lub sijhawm zoo, lub hnab yas polyurethane yog qhov yuav tsum tau ua tib zoo saib xyuas qhov teeb meem, hauv cov txheej txheem ntawm kev tso nyiaj, yog tias qhov tso nyiaj tsis zoo, lossis tsis yog, yog li nws yooj yim ua rau pov tseg ntawm cov hnab yas polyurethane, rau qhov tshwm sim ntawm cov xwm txheej zoo li no, peb yuav koom ua ke hnub no kom kawm paub cov khoom lag luam yas hnab yog yuav ua li cas thiaj li tso nyiaj tau.
Idle polyurethane cots yuav ua li cas khaws cia kom raug: cov menyuam yaus polyurethane yuav tsum tau muab ntxuav, kaw nrog yas zaj duab xis colloidal, ntawm lub thav duab tsis siv polyurethane, yuav tsum tsis txhob muaj ob peb qhov sib dhos ua ke hauv ib thooj lossis sawv ntsug tiv thaiv phab ntsa, yog li tsis txhob ua poob colloidal. Khib tsis siv neeg polyurethane cov menyuam hauv cov txheej txheem kev thauj mus los rau kev ua thiab pov tseg, tsis txhob cuam tshuam qhov siab lossis hnyav, ua kom cov tub ntxhais tsis yog ib feem tseem ceeb, tsis khoov, rau qhov siv cov tub ntxhais ib txwm muaj.
Polyurethane cots nrog lub zog ua haujlwm siab, tiv taus kev laus thiab roj tsis kam kuj tseem zoo heev, feem ntau siv hauv ntawv, tshuaj fiber, ntoo ua, ua yas thiab lwm yam tshuab, ntau lub tuam txhab yuav yuav qee cov polyurethane cov menyuam rau hnub los nag, raws li saum toj no tsis ua haujlwm polyurethane cots yog txoj hauv kev khaws cia, tuaj yeem polyurethane cots puas tsuaj.
