Kev Taw Qhia Txog Zinc Borate

Zinc borate yog ib yam khoom siv hluav taws xob uas ua tau zoo heev, tsis ua rau ib puag ncig puas tsuaj, uas muaj cov yam ntxwv ua rau hluav taws kub, tiv thaiv pa luam yeeb thiab tiv thaiv kom tsis txhob ntws. Nws cov khoom tseem ceeb yog 2ZnO·3B₂O₃·3.5H₂O, thiab nws zoo li hmoov dawb lossis daj daj tsis sib xws lossis rhombic. Nrog kev ruaj khov tshuaj lom neeg zoo heev thiab kev hloov pauv tau yooj yim, nws yog cov khoom siv zoo tshaj plaws rau kev txhim kho kev nyab xeeb hauv kev lag luam roj hmab thiab yas, txheej, hlau thiab cable.

Cov khoom no muaj kev ruaj khov zoo heev, maj mam poob dej siv lead ua tsuas yog siab tshaj 320 ℃. Nws tsis lwj lossis valolit hauv cov txheej txheem ua haujlwm kub siab xws li extrusion, txhaj tshuaj molding thiab txau, thiab tuaj yeem tswj tau qhov ua haujlwm hluav taws kub ruaj khov. Nws tsis yaj hauv cov kuab tshuaj organic xws li dej, ethanol, benzene thiab acetone, tab sis yooj yim yaj hauv hydrochloric acid, sulfuric acid thiab dimethyl sulfoxide (DMSO). Nrog kev sib xyaw zoo heev, nws muaj kev sib raug zoo nrog ntau yam substrates xws li PVC, PE, PP, roj hmab thiab resin, thiab tsis cuam tshuam rau qhov tsos, lub zog kho tshuab lossis kev laus ntawm cov khoom tiav tom qab ntxiv.

Hais txog lub tshuab ua kom nplaim taws tsis kam, zinc borate txo qhov kub los ntawm kev rhuav tshem cov pa roj uas kub heev, tso cov dej siv lead ua kom cov pa roj uas yooj yim hlawv tawm, thiab tsim cov txheej tiv thaiv iav ntom ntom kom cais cov pa oxygen, yog li ua tiav peb yam txiaj ntsig ntawm kev nplaim taws tsis kam, kev tswj pa luam yeeb tsis kam thiab kev tiv thaiv dej ntws. Nws tuaj yeem siv ua ke nrog txhuas hydroxide, magnesium hydroxide thiab organophosphorus nplaim taws tsis kam kom txhim kho qib nplaim taws tsis kam ntawm cov ntaub ntawv. Nws kuj tseem tuaj yeem hloov ib feem ntawm cov nplaim taws tsis kam ib txwm muaj xws li antimony trioxide, ua kom cov nqi mis zoo dua.

Cov khoom no tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis muaj kuab paug, ua raws li kev tiv thaiv ib puag ncig thoob ntiaj teb thiab cov qauv hluav taws kub. Nws siv dav hauv cov teb xws li cov xov hlau thiab cov cables, cov txheej tiv thaiv hluav taws, cov kav dej yas, cov khoom siv roj hmab thiab cov polyester resins tsis muaj roj. Txawm hais tias rau kev hloov kho cov khoom siv siab hauv kev tsim khoom lag luam lossis kev ua raws li kev nyab xeeb ntawm cov khoom siv pej xeem, zinc borate tuaj yeem muab cov kev daws teeb meem hluav taws kub txhim khu kev qha, pab cov tuam txhab ua tiav kev txhim kho khoom thiab ua raws li kev tsim khoom.
