Puas Yog Tus Qauv Roj Hmab?

Cov ceg ntoo sib xyaw: Cov kev sib sau ua ke ntawm cov ceg ntawm cov roj hmab macromolecule saw, thiab cov roj hmab fenders tsim cov gel. Gels ua kev cuam tshuam rau cov roj hmab ua tiav thiab ua tiav. Thaum sib xyaw, ntau yam kab mob sib xyaw feem ntau tsis tuaj yeem nkag mus rau thaj chaw gel, ua rau thaj chaw hauv zos, thiab cov roj hmab fenders tsis tuaj yeem tsim kev txhawb nqa thiab sib txuas sib txuas, ua ib qho tsis muaj zog ntawm cov khoom.

Tus qauv hla kev sib txuas: Cov kab lev tawm nrog cov kab sib txuas los sib txuas los ntawm kev sib txuas ntawm qee cov atoms lossis pawg ntawm atoms, thiab cov roj hmab fenders tsim cov kab uas muaj peb-seem hauv lub network. Qhia tau hais tias nrog kev nce qib ntawm cov txheej txheem vulcanization, tus qauv no txuas ntxiv mus. Zoo li roj hmab fenders, lub zog dawb muaj peev xwm ntawm cov saw ntu yog txo, plasticity thiab elongation yog txo, lub zog, elasticity thiab hardness ntawm cov roj hmab fenders yog nce, lub compression txheej thiab o poob qib poob.

Kev Tshaj Tawm: Kev sib cais ntawm cov ceg ntawm cov roj hmab macromolecule saw los ua ib lub gel. Cov roj hmab fender gel yog qhov cuam tshuam rau kev ua tau zoo thiab ua tiav ntawm insulating roj hmab los xij. Thaum lub sijhawm sib xyaw, ntau yam kab mob sib xyaw feem ntau tsis tuaj yeem nkag mus hauv thaj chaw gel, ua rau thaj chaw hauv zos, thiab cov roj hmab fenders tsis tuaj yeem tsim kev txhawb nqa thiab sib txuas sib txuas, ua ib qho tsis muaj zog ntawm cov khoom.

Cov kab tsim tawm: cov qauv siv dav dav ntawm cov roj hmab tsis kaw. Vim yog qhov loj molecular phaus, macromolecular saw muaj ib qho kev sib tw ntawm curvilinear pawg tsis muaj quab yuam sab nraud los ntawm cov roj hmab fender. Thaum kev siv dag zog sab nraud thiab sab nraud quab yuam raug tshem tawm, qhov hloov ntawm cov roj hmab fender xov pawg hloov, cov roj molecular saw rov qab, thiab muaj lub zog zoo los rov ua dua. Qhov no yog keeb kwm ntawm lub siab elasticity ntawm roj hmab.
