Roj Hmab Lub Koom Haum Tus Neeg Sawv Cev tseem hu ua Vulcanizing Tus Neeg Saib Xyuas Haujlwm. Ib qho kev siv hluav taws xob lossis cov organic siv los ua kom muaj vulcanization accelerator nquag. Nws tuaj yeem ua kom muaj peev xwm loj heev ntawm lub peev xwm ntawm tus tsuj roj, txo qis tus ntsuas, thiab lub sijhawm ua kom ntev. Feem ntau ntawm cov inorganic cov roj ntsha yog hlau oxides, hydroxide, xws li cov pa roj ntsha, thiab lwm yam, thiab lwm yam. roj hmab.

Roj Hmab Ntxiv: Cov khoom kom ntxaws, qhov zoo, thiab cov ntawv thov

1. Zinc Oxide (ZNO)

Khoom:

• Cov hmoov dawb, tsis muaj ntxhiab nrog lub ntiajteb txawj nqus siab (5.6 g / cm³).

• Melting taw tes: 1,975 ° C; Cov ntsiab lus tsis zoo: 2.008-2.029.

• Siab reactivity ua vulcanization activator.

• UV-thaiv thiab cov tshuaj tiv thaiv antimicrobial.

Qhov Zoo:

• Ua nrawm nrawm sulfur vulcanization (txo lub sijhawm kho kom txog 20-30%).

• Txhim kho cov khoom siv txhua yam (tensile lub zog + 15-25%, elongation thaum so + 10-15%).

• FDA pom zoo rau cov ntawv thov hu rau zaub mov (21 CFR 172.480).

• Tus phooj ywg ib puag ncig (tsis muaj tshuaj lom, rov ua dua tshiab).

Cov Ntawv Thov:

• Cov log tsheb hlau: steel-belted radial log tsheb carcasses (txhim kho kev nplaum ntawm roj hmab thiab hlau).

• Cov khau: Outsole tebchaw (txhim kho kom tsis kam, Astm D5963: 50-80 mm³ ploj).

• Kev kho mob: Kev phais cov hnab looj tes looj hnab looj tes (tshuaj tiv thaiv kab mob antimicrobial, ASTM E2149).

• Cov nplaum: Roj hmab-rau-hlau kev sib khi (nce tev lub zog los ntawm 30-40%).

2. Phenolic Resin

Khoom:

• Th thermosetting polymer nrog high crosslink ntom.

• Thaum tshav kub kub tiv: kev siv txuas ntxiv siv txog 180 ° C (sib qev 250 ° C).

• High Rigidity (Modulus: 2-4 GPA) thiab seem ruaj khov.

• Tshuaj lom neeg tiv thaiv cov kua qaub, hauv paus, thiab cov kuab tshuaj.

Qhov Zoo:

• Muab cov txheej txheem ntxiv (nce hardness los ntawm 10-20 ntug dej a).

• Nplaim taws retardant (ul94 v-0 kev ntaus nqi tsis muaj halogen ntxiv).

• Raug nqi zoo piv rau cov tshwj xeeb thermoplastics.

• Customizable kho cov tshuab (acid-catalyzed lossis tshav kub-ua kom tiav).

Cov Ntawv Thov:

• Cov log tsheb: cov tebchaw saum toj (txhim kho kev txiav tawm, ittm D624).

• Koj txoj siv sia: Tus siv tawv conveyor rau qhov chaw kub-ib puag ncig (xws li, cov nroj tsuag xis mas cog).

• Cov ntaub ntawv sib txhuam: Cov ntaub qhwv paj (tswj coefficient ntawm kev txhuam ntawm 0.35-0.45 nyob rau hauv 200 ° C).

• Foundry: Cov xuab zeb tseem ceeb (txo cov roj hloov pauv thaum ua thawj).
