Ua rau ntawm huab cua npuas hauv silica gel raj

Cov khoom siv silicone zoo yog tsim tam sim ntawd tom qab tawm hauv lub Hoobkas, ua tau raws li tus qauv rau kev siv tsis tu ncua, thiab muaj lub ntsej muag du, ruaj khov, thiab tuaj yeem tiv taus ntau yam kev sim.

 

Cov khoom siv silicone tsis tuaj yeem rov ua dua rau kev tsim khoom.Thaum molded, cov khoom siv silicone tsis tuaj yeem thim rov qab.Yog tias cov khoom siv silicone molded muaj qhov tsis zoo, nws ntsib cov khoom seem.Yog tias nws tsuas muaj qhov tsis zoo me ntsis, nws tseem tuaj yeem kho raws li cov khoom siv rov ua dua tshiab.Tom qab ntawd, qee lub raj silicone yuav muaj blistering tom qab ntau lawm.Yog vim li cas?

 

Muaj ob qhov laj thawj vim li cas cov raj silicone tuaj yeem ua npuas:

 

1. Raw Material Teeb meem: Nws kwv yees tias pob tshab dawb carbon dub yog impure los yog tov nrog lwm yam dawb carbon dub.

 

2. Cov teeb meem coking: sib tov tsis sib xws ntawm cov khoom siv roj hmab, tsis muaj peev xwm ua kom tsis muaj zog, thiab tsis muaj kev tswj xyuas qhov kub thiab lub sijhawm.

 

3. Phab ntsa thickness yog tuab heev thiab hardness yog mos heev.

 

Cov kev daws teeb meem tshwj xeeb:

 

1. Rau cov khoom siv raw: xaiv cov pob tshab dawb carbon dub nrog cov purity siab dua, ntxuav nws nrog lub tshuab kneading, thiab tom qab ntawd ua kom cov nplaum pob tshab.

 

2. Rau coking txheej txheem teeb meem: tswj lub kneading kub thiab lub sij hawm, ncua lub thawj kneading lub sij hawm los ntawm 5-10 feeb, thiab ces tso cov kua nplaum rau kev soj ntsuam.

 

3. Yog tias cov phab ntsa tuab tuab, sim xaiv cov khoom siv silicone nrog cov hardness siab.

 

Tsis tas li ntawd, peb tuaj yeem xyuam xim rau cov ntsiab lus hauv qab no thaum khaws cov roj hmab silicone roj hmab:

 

1. Ntim zoo los tiv thaiv plua plav thiab oxidation.

 

2. Khaws qhov cua thiab qhuav kom tsis txhob muaj pwm.

 

3. Siv nyob rau ntawm qhov kub thiab txias tsis pub dhau lub sijhawm teev tseg.

 

4. Muab lub raj silicone tso rau ntawm chav tsev kub kom tsis txhob tshav ntuj.
