Qhov txawv ntawm cov pos hniav thiab yas yog dab tsi?

Qhov txawv ntawm cov pos hniav thiab yas yog dab tsi?Yas thiab roj hmab muaj qhov sib txawv tseem ceeb hauv qhov xwm txheej, feem ntau cuam tshuam txog hom deformation, elasticity, molding txheej txheem thiab lwm yam peb yam:

(1) Hom deformation: thaum raug rau sab nraud quab yuam, yas deformation yuav tshwm sim, uas yog, nws tsis yooj yim rau rov qab mus rau qub duab lossis lub xeev;Cov roj hmab yuav dhau los ua elastic deformation, uas yog, nws tuaj yeem rov qab mus rau nws qhov qub qub tom qab tshem tawm cov quab yuam sab nraud.

(2) Elasticity: Cov elasticity ntawm cov yas feem ntau yog me me, thiab nws cov peev xwm rov qab tau tom qab deformation tsis muaj zog dua li cov roj hmab.Raws li ib txwm muaj, qhov elasticity ntawm cov yas yog tsawg dua 100%, thiab cov roj hmab elastic tuaj yeem ncav cuag 1000% lossis siab dua.

(3) Moulding txheej txheem: yas hauv cov txheej txheem molding, thaum ua tiav, nws cov duab yog kho, nws nyuaj rau hloov;Cov roj hmab kuj yuav tsum tau mus dhau cov txheej txheem vulcanization tom qab tsim, kom cov qauv tshuaj ntawm cov roj hmab ruaj khov thiab kev ua haujlwm zoo dua.

Ntxiv rau qhov sib txawv saum toj no, muaj peb qhov sib txawv ntawm cov pos hniav thiab yas:

(1) Muaj pes tsawg leeg thiab qhov chaw: yas yog tsuas yog ua los ntawm fossil fuels xws li roj av thiab yog cov khoom tsim los ntawm tib neeg;Cov pos hniav, ntawm qhov tod tes, yog ntuj, muab tau los ntawm exudates los ntawm ntau yam ntoo.

(2) Lub cev lub cev: cov pos hniav feem ntau muaj qee yam viscosity thiab elasticity, thaum cov yas yuav muaj cov khoom sib txawv xws li softness, hardness thiab brittleness raws li hom tshwj xeeb.

(3) Siv: Vim nws lub ntuj viscosity thiab elasticity, cov pos hniav feem ntau siv rau kev sib khi, sib khi thiab lwm yam khoom siv;Daim ntawv thov ntawm cov yas yog dav heev, xws li ntim khoom, khoom siv hauv tsev, khoom siv hluav taws xob thiab lwm yam.

Hauv cov ntsiab lus, yas thiab roj hmab muaj qhov sib txawv tseem ceeb hauv hom deformation, elasticity, molding txheej txheem, thiab lwm yam, thaum cov pos hniav thiab yas yog qhov sib txawv ntawm cov khoom xyaw thiab qhov chaw, lub cev thiab kev siv.Cov kev sib txawv no tso cai rau peb xaiv cov khoom tsim nyog raws li peb cov kev xav tau hauv lub neej niaj hnub thiab kev tsim khoom lag luam.Yog xav paub ntxiv txog "Qhov txawv ntawm cov pos hniav thiab yas", nws raug nquahu kom sab laj nrog cov ntaub ntawv tseem ceeb lossis sab laj nrog tus kws tshaj lij cov ntaub ntawv.
