Kev hloov pauv ntawm lub zog extrusion, cov khoom tsis muaj zog yuav maj mam txo lub zog, siab hardness yuav nce, thiab 5-10 degrees ntawm qhov sib txawv yuav muaj qhov sib txawv extrusion hloov.

Qhov kev hloov ntawm cov kua muag tsis kam, qhov siab dua qhov hardness ntawm cov khoom tsim kua muag kuj yuav tsis muaj zog, tshwj xeeb tshaj yog nrog cov khoom ntawm lub kaum sab xis yog nquag tsim kua muag, qhov qis hardness ntawm lub kua muag yog qhov zoo dua, qhov sib txawv hardness ntawm lub kua muag yog txawv.

Kev ntxhov siab tsis tu ncua ua rau deformation. Kev ntxhov siab tsis tu ncua yog qhov tseem ceeb tswj kev ntsuas ntawmsilicone roj hmabcov khoom, uas muaj ib tug tej yam correlation nrog hardness.

Hnav tsis kam thiab qaug zog hloov pauv, qhov sib txawv hardness ntawm cov khoom hauv kev hnav tsis kam thiab qaug zog muaj qhov sib txawv, feem ntausilicone roj hmabcov khoom siv nrog qhov nce ntawm crystallinity hardness, lub sij hawm ntev khiav-hauv yuav cuam tshuam rau qaug zog poob hnav tsis txaus.

Qhov sib txawv ntawm elasticity, elasticity yog ib qho tseem ceeb ntawm cov khoom siv silicone, yog li qhov sib txawv hardness ntawm cov khoom muaj kev cuam tshuam rau txhua daim ntawv thov sib txawv ntawm cov khoom, thiab qhov hardness ntawm qhov sib txawv loj heev yuav ua rau kev siv tag nrho. cov khoom, thiab txawm cuam tshuam tag nrho txhua qhov txuas!

Ntau tus neeg siv khoom tsis raug qhia kom raug siv cov tawv tawv thaum yuav khoomsilicone roj hmabcov khoom. Tsis muaj qhov yuav tsum tau ua rau hardness ntawm cov ntaub ntawv, tab sis kev xaiv ntawm hardness ntawmsilicone roj hmabcov khoom muaj feem cuam tshuam rau kev siv ntawm tag nrho cov khoom
