Dab tsi yog hom hnav ntawmcov khoom sib txhuam?
Cov ntawv sib txhuam tam sim no yuav tsum tau hnav-tiv taus thaum ntxov ntawm kev tsim khoom, tab sis cov khoom tsis ncaj ncees, thiab qhov yuav tsum tau hnav-tiv taus qib sib txawv. Hnav-resistant yog tib yam khoom, thiab muaj ntau ntau yam ntawm peb cov ntaub ntawv sib txhuam. Thiab dab tsi yog hom hnav ntawm peb cov ntaub ntawv sib txhuam?
1. Adhesive hnav, ntau yam uas tau hloov tshiab txhuam daim hlau. Thaum cov khoom sib txhuam ntawm qhov chaw rub tawm ntawm cov khoom siv dual, cov ntsiab lus tsis sib xws ntawm cov khoom sib txhuam ntawm qhov sib txhuam thiab sib tsoo, ua rau lub zos overheating thiab softening thiab shearing poob, tev tawm ntawm qhov chaw, ua rau cov nplaum hnav.
2. Txiav thiab abrasive hnav, thaum lub hardness ntawm ob qhov chaw rub tawm ib leeg yog qhov sib txawv heev, thaum lub sij hawm kev sib txhuam, cov pob ntawm cov khoom tawv tawv yuav raug nias rau hauv cov khoom softer, thiab softer. sab yuav hnyav hnyav. Obviously, yog tias cov khoom sib txhuam thiab cov khoom sib tw yog mos heev, txiav thiab abrasive hnav yuav yooj yim tshwm sim.
3. Kev qaug zog hnav, qhov adhesion ntawm resin thiab reinforcing tus neeg sawv cev yog ib qho tseem ceeb ntawm kev ua haujlwm qaug zog ntawm qhov chaw, thiab kev qaug zog ib txwm yog tshwm sim los ntawm kev puas tsuaj ntawm adhesion ntawm resin thiab reinforcing tus neeg sawv cev ntawm cov ntsiab lus kev ntxhov siab. Nrog rau kev puas tsuaj ntxiv, cov resin yuav dhau los ua hmoov thiab kev sib txuas yuav ploj, uas ua rau muaj kev hnav thiab kev puas tsuaj ntawm cov khoom sib txhuam.
4. Thermal hnav yog cov khoom poob los ntawm oxidation los yog thermal decomposition ntawm cov organic teeb meem vim kev sib txhuam thaum tshav kub kub tsim.
