Silicone ua npuas ncauj, tseem hu ua molded silicone, yog ib tug ntxeem tau roj hmab structural khoom ua los ntawm silicone roj hmab raws li ib tug hauv paus khoom thiab ua los ntawm foaming.

 

　　Nrog rau kev txhim kho txuas ntxiv thiab hloov kho cov tshuab foaming, tab sis kuj vim nws cov yam ntxwv zoo dua, daim ntawv thov thaj chaw muaj ntau thiab ntau dua, xws li sealing strips, cushioning pads, siv gaskets, kev co cais cov ntaub ntawv, cov khoom siv tiv thaiv thiab lwm yam.

 

Txoj cai ntawm silicone ua npuas ncauj

 

　　Foaming silicone roj hmab, lub hauv paus ntsiab lus yog ntxiv foaming tus neeg sawv cev nyob rau hauv lub xaiv silicone roj hmab compound, nyob rau hauv lub siab lub xeev cua sov vulcanization silicone roj hmab ua npuas ncauj, roj hmab expansion los tsim ib tug sponge zoo li npuas qauv. Lub ntsiab yam tseem ceeb uas txiav txim siab thiab cuam tshuam cov qauv ntawm cov npuas yog cov roj uas tsim los ntawm tus neeg sawv cev tshuab, qhov nrawm nrawm ntawm cov roj hauv cov roj hmab, viscosity ntawm cov roj hmab thiab qhov ceev ntawm vulcanization. Txhawm rau ua kom zoo dua cov khoom lag luam silicone ua npuas ncauj, kev xaiv ntawm hom foaming agent thiab roj hmab vulcanization system yog qhov tseem ceeb.

 

　　Silicone ua npuas ncauj txheej txheem

 

　　Silicone ua npuas ncauj yuav tsum tau mus los ntawm ib tug series ntawm ntau lawm txheej txheem, ua technology, txhua qhov txuas yuav muaj kev cuam tshuam rau lub tiav lawm silicone ua npuas ncauj.

 

　　1, plasticizing (uas yog, plasticity ntawm raw roj hmab refining, uas yog, tsis muaj additives nyob rau hauv lub qhib refining tshuab refining. Cia cov roj hmab soften kom yaj mus rau hauv tus neeg sawv cev koom tes (los npaj rau kev sib tov).

 

　　Lub ntsiab ntawm cov yas refining ntawm cov roj hmab nyoos yog ua kom tawg thiab rhuav tshem cov macromolecular saw ntawm roj hmab, txhim kho cov yas ntawm cov roj hmab, thiab ua kom sib xyaw thiab sib xyaw ntawm cov khoom sib xyaw yooj yim dua. Hauv kev tsim cov khoom siv roj hmab foamed, cov roj hmab nyoos yog cov yas tag nrho, yuav ua rau cov roj hmab yas zoo dua, yooj yim dua los ua kom cov npuas qhov sib xws, tsis tshua muaj ntom, cov khoom me me.

 

2, sib tov, uas yog, cov roj hmab yas los ntxiv ntau yam ntawm cov neeg ua hauj lwm (additives) rau refining.

 

Cov txheej txheem sib xyaw yog ntau yam ntawm cov neeg ua haujlwm hauv cov roj hmab nyoos (lossis plasticizing roj hmab) hauv cov txheej txheem ntawm kev tsis sib xws. Raws li nrog kev sib xyaw ntawm lwm cov ntaub ntawv polymer, txhawm rau ua kom cov khoom sib xyaw ua ke sib xyaw ua ke hauv cov roj hmab nyoos, yuav tsum siv cov khoom siv zog ua haujlwm ntawm lub tshuab ua kom zoo. Txawm li cas los xij, vim tias cov khoom siv roj hmab muaj ntau cov khoom sib koom ua ke, cov khoom sib txawv ntawm cov neeg ua haujlwm sib koom ua ke sib txawv heev, thiab kev cuam tshuam ntawm kev sib koom ua ke ntawm cov txheej txheem sib xyaw, qib ntawm dispersion, thiab cov qauv ntawm cov roj hmab compound kuj zoo heev, yog li cov txheej txheem sib xyaw ntawm cov roj hmab yog qhov nyuaj dua li ntawm lwm cov ntaub ntawv polymer.

 

Cov txheej txheem sib tov muaj qhov tseem ceeb heev ntawm kev ua haujlwm ntawm cov khoom siv roj hmab. Kev sib xyaw tsis zoo, cov roj hmab yuav tsis sib luag ntawm kev sib xyaw ua ke, plasticity ntawm cov roj hmab siab dhau los yog qis dhau, kub hnyiab, Frost thiab lwm yam tshwm sim, uas yuav tsis tsuas yog ua rau calendering, nias, molding thiab vulcanization txheej txheem tsis tuaj yeem nqa. tawm ib txwm, tab sis kuj ua rau kev ua tau zoo ntawm cov khoom tiav degradation, thiab tej zaum yuav ua rau cov khoom ntawm qhov kawg ntawm lub neej. Yog li ntawd, kev sib tov yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev ua cov roj hmab.

 

　　3,Chaw nres tsheb

 

　　Roj hmab hauv kev sib xyaw ua tiav, yuav tsum tau muab tso rau lub sijhawm tsim nyog, kom muaj ntau yam additives hauv kev sib xyaw ntawm cov roj hmab tag nrho dispersed, roj hmab additives dispersed ntau tusyees, stability ntawm cov khoom loj, qib ntawm smoothness ntawm cov khoom. nto, qhov degree ntawm uniformity ntawm npuas kuj yog qhov zoo dua.

 

　　3,Kub

 

　　Roj hmab ua npuas ncauj yog qhov kub thiab txias, tib hom roj hmab, cov nyhuv foaming tsis zoo ib yam ntawm qhov sib txawv ntawm qhov kub thiab txias, vim hais tias lub foaming system thiab vulcanization system yog rhiab heev rau qhov kub ntawm qhov sib txawv degrees, qhov system hloov, qhov sib piv ntawm qhov sib txawv, cov nyhuv kuj txawv.

 

　　4, pwm

 

　　Foamed roj hmab cov khoom tom qab ua thiab molding txoj kev yog extrusion molding, molding, phaj molding, thiab lwm yam., raws li qhov yuav tsum tau cov qauv ntawm cov khoom tiav, specifications, ntev, loj, zoo, hardness, xim yog txawv, raws li zoo raws li qhov tshwj xeeb cov kev xav tau ntawm cov duab kos, koj tuaj yeem ua tsis tau raws li tus qauv tsim kho.
