Tej teeb meem nyob rau hauv cov txheej txheem ntau lawm ntawmPU imitation ntoo khoomyog:1. Epidermal npuas:Cov xwm txheej tsim khoom tam sim no yeej muaj, tab sis tsuas muaj qee qhov teeb meem xwb.2. Epidermal kab dawb:Qhov teeb meem hauv kev tsim khoom tam sim no yog yuav ua li cas txo cov kab dawb thiab kho qhov chaw uas cov kab dawb tshwm.3. Daim tawv nqaij hardness:Raws li kev cai sib txawv ntawm cov neeg siv khoom, tam sim no tsis muaj tus qauv tseeb.Kev txheeb xyuas ntawm cov teeb meem saum toj no yog raws li hauv qab no: 1. Epidermal npuas:Nyob ntawm qhov chaw thiab qhov tshwm sim, qhov ua rau txawv.Tej yam laj thawj yog:(1) Teeb meem nrog phom foaming:ib.Tsim tawm thaum lub sijhawm sib xyaw: sim txo cov npuas uas tsim tawm thaum cov khoom foaming ntws tawm ntawm lub taub hau phom, xws li kev sib xyaw tsis zoo thiab cua nkag los ntawm rab phom taub hau.b.Kev sib xyaw ceev (rau cov tshuab tsis tshua muaj siab): qhov siab dua, qhov zoo dua, thiab qhov me me ntws, qhov zoo dua.c.Tsis txhob tsuag cov tailings ntawm cov khoom.d.Cov khoom siv kub yog siab, cov tshuaj tiv thaiv yog ceev, thiab cov npuas yuav raug txo (feem ntau nyob rau lub caij ntuj no).e.Qhov kev faib ua feem ntawm cov khoom siv dub yog siab, huab cua npuas nce, thiab lub siab ntawm lub tank cia ruaj khov.f.Cov av thiab plua plav yog sib xyaw rau hauv lub taub hau phom foaming.(2) Kev cuam tshuam ntawm pwm:ib.Cov pwm kub yog siab, cov npuas yuav raug txo.b.Pwm tso cov nyhuv, tsim nyog inclination lub kaum sab xis.c.Cov qauv pwm txiav txim siab tias qee cov khoom muaj ntau dua, thiab qee yam khoom tsawg dua.d.Pwm nto smoothness thiab pwm nto huv si.(3) Txheej txheem tswj:ib.Cov nyhuv ntawm txhuam hniav thiab tsis txhuam hniav, kev txhaj tshuaj ntau dua thiab tsis muaj npuas.b.Kev kaw pwm lig yuav txo cov npuas npuas.c.Txoj kev txhaj tshuaj thiab kev faib cov khoom siv raw hauv pwm.(4) Kev cuam tshuam ntawm kev tso tawm tus neeg sawv cev:ib.Silicone roj tso tawm tus neeg sawv cev muaj ntau npuas thiab tsawg waxy npuas2. Qhov teeb meem ntawm kab dawb ntawm cov khoom epidermis:Thaum cov khoom siv raw yog txhaj rau hauv pwm, yuav muaj qhov sib txawv ntawm lub sijhawm, yog li yuav muaj qhov sib txawv ntawm lub sijhawm thaum cov khoom siv raw pib hnov mob, yog li cov kab dawb yuav raug tsim tawm ntawm qhov sib tshooj ntawm qhov sib txuas ua ntej thiab tom qab. tshuaj tiv thaiv.Cov laj thawj tseem ceeb rau nws yog: ⑴ Pwm teeb meem:ib.Thaum pwm kub yog 40-50 ℃, cov kab dawb yuav txo.b.Lub kaum sab xis ntawm cov pwm yog txawv, thiab txoj hauj lwm ntawm cov kab dawb kuj txawv.c.Qhov kub hauv zos ntawm pwm kub yog siab dhau, ua rau lub sijhawm sib txawv ntawm cov khoom siv raw, ua rau cov kab dawb.d.Yog tias cov khoom loj dhau los yog tuab heev, cov kab dawb yuav nce ntxiv.e.Cov pwm yog ib nrab dej stained thiab tso tawm tus neeg sawv cev tsis qhuav, ua rau cov kab dawb.⑵ Foaming phom:ib.Qhov kub ntawm cov khoom siv yuav txo tau cov kab dawb, thiab qhov chaw uas cov kab dawb tshwm thaum qhov kev faib ua feem ntawm cov khoom dub yog siab dua.b.(Lub tshuab tsis tshua muaj siab) Lub siab ceev ntawm rab phom taub hau, qhov sib xyaw ua haujlwm zoo, thiab cov kab dawb yuav raug txo.c.Yuav muaj kab dawb ntawm lub taub hau thiab tus Tsov tus tw ntawm cov khoom.(3) Txheej txheem tswj:ib.Qhov nce ntawm cov khoom siv raw infusion yuav txo cov kab dawb.b.Tom qab txhaj tshuaj, txhuam hniav yuav txo cov kab dawb.3. Khoom hardness:ib.Qhov ceev ntawm cov khoom siv raw yog siab, hardness ntawm cov khoom nce, tab sis tus nqi ntawm infusion nce.b.Qhov feem ntawm cov khoom siv dub yog siab heev.Epidermal hardness nce.c.Thaum cov pwm kub thiab cov khoom kub yog siab, lub hardness ntawm cov khoom yuav txo.d.Tus neeg sawv cev tso tawm yuav txo cov tawv nqaij tawv, thiab cov xim hauv pwm yuav ua rau kom tawv nqaij tawv.Cov khoom tsim nyog yuav tsum tau tswj xyuas cov khoom siv, cov khoom siv raw, cov txheej txheem, pwm, thiab lwm yam, yog li nws raug pom zoo kom nrhiav kev koom tes los ntawm cov neeg muag khoom ntawm cov khoom siv polyurethane hauv cov txheej txheem tsim khoom.
