Lub luag haujlwm tseem ceeb ntawm cua sov shrink tubing nyob rau hauv ib lub voj voog yog los tiv thaiv cov khoom siv tseem ceeb thiab circuits los ntawm kev puas tsuaj thiab cuam tshuam. Txawm hais tias nws tsis muaj kev cuam tshuam tshwj xeeb rau kev ua haujlwm ntawm lub voj voog, nws feem ntau yog lub ntsiab lus tseem ceeb uas txiav txim siab qhov ua tiav lossis tsis ua tiav ntawm tag nrho cov qauv tsim. Nrog rau kev loj hlob sai ntawm kev lag luam hluav taws xob, nplaim-retardant tshav kub shrink tubing kuj yog inseparable ntawm electronics kev lag luam, ntau thiab ntau cov khoom siv hluav taws xob yuav tsum tau siv cov nplaim hluav taws kub hnyiab tubing rau kev tiv thaiv. Cov nplaim retardant ua ntawm lub tshav kub shrink tube, thaum tawm tsam los ntawm qhov hluav taws kub sab nraud, tuaj yeem thaiv tau zoo, ncua lossis nres qhov kis ntawm cov nplaim taws, kom ua tiav cov nyhuv ntawm cov nplaim hluav taws.
Cov nplaim hluav taws kuj tseem muab faib ua ntau hom, Raws li txoj kev siv tau muab faib ua cov nplaim hluav taws xob ntxiv thiab cov nplaim hluav taws xob reactive. Nplaim retardants feem ntau yog cov nplaim hluav taws kub nyhiab thiab cov nplaim hluav taws tsis zoo, halogen nplaim retardants (organic chlorides thiab organic bromides), thiab tsis-halogen. Cov organic yog ib tug xov tooj ntawm cov nplaim hluav taws uas sawv cev los ntawm bromine system, phosphorus thiab nitrogen, nitrogen thiab liab phosphorus, thiab compounds. Inorganic feem ntau yog antimony trioxide, magnesium hydroxide, aluminium hydroxide, silicon system, thiab lwm yam hluav taws kub retardant systems.
Cov nplaim hluav taws kub hnyiab tau siv los ua cov monomer los koom rau hauv cov tshuaj tiv thaiv polymerization kom cov polymer nws tus kheej muaj cov nplaim hluav taws kub.. Qhov zoo dua yog tias nws muaj kev cuam tshuam tsawg dua ntawm kev ua haujlwm ntawm cov ntaub ntawv polymer thiab muaj cov nplaim hluav taws kub ntev. Los ntawm ntau yam ntawm nplaim retardants, nplaim retardants ntawm tshav kub shrinkable hlab nyob rau hauv kev ua lag luam feem ntau muab faib ua peb hom: halogen nplaim retardants, liab phosphorus nplaim retardants, thiab magnesium hydroxide nplaim retardants. Vim yog cov nplaim hluav taws sib txawv, cov cua sov-shrinkable raj tsim los ntawm kev ntxhib los mos, tsos, tsw, thiab tus nqi sib txawv.
Halogen nplaim-retardant tshav kub shrinkable raj: Nws tus kheej nrog me ntsis tsw, tom qab lub tshav kub shrinkage yuav tshwm sim yuav tsum muaj teeb meem rau huab cua, belongs rau hom khoom tsis zoo ib puag ncig. Liab phosphorus nplaim hluav taws kub-shrinkable raj: Nws tus kheej tsw ntxhiab, vim yog liab phosphorus muaj pes tsawg leeg, nyob rau hauv cov ntaub ntawv ntawm cua sov thiab dej, vim phosphorus yog ib qho khoom noj, qhov siab dua cov ntsiab lus yuav ua eutrophication, ua rau muaj kev loj hlob sai ntawm algae. Qhov no yuav ua rau cov pa oxygen hauv dej kom cov nroj tsuag dej thiab tsiaj tuag, ntau algae kuj tuag vim tsis muaj oxygen lwj, thiaj li hais tias lub cev dej kiag li poob rau kev siv ntawm kev ua haujlwm. Yog li ntawd, ua ib feem ntawm kev tswj hwm kev ua qias tuaj ntawm dej, phosphorus txwv tsis pub yog ib qho tseem ceeb ntsuas.
Magnesium hydroxide nplaim retardant tshav kub shrink tube: magnesium hydroxide decomposition tshwm sim thaum rhuab kom nqus cua sov los ntawm sab nrauv ntawm cov khoom incendiary los ua cov nplaim hluav taws kub.. Tib lub sijhawm tso tawm, ntau cov dej dilution ntawm oxygen nyob rau saum npoo ntawm incendiary, decomposition ntawm cov tsim active magnesium oxide txuas rau saum npoo ntawm cov ntaub ntawv combustible thiab ntxiv obstructing incineration. Magnesium hydroxide nyob rau hauv tag nrho cov nplaim retardant txheej txheem tsis tsuas yog tsis muaj teeb meem tshuaj, thiab decomposition ntawm cov khoom nyob rau hauv cov nplaim retardant tib lub sij hawm kuj yuav nqus tau ntau cov roj hmab, yas, thiab lwm yam polymers’ incineration ntawm cov pa phem thiab pa taws.
Nyob rau tam sim no: Tebchaws Meskas, Tebchaws Askiv, Nyiaj txiag, thiab lwm lub teb chaws tsim nyob rau hauv txoj kev loj hlob thiab kev siv cov nplaim hluav taws kub-shrinkable raj nyob rau hauv txoj hauj lwm ua. Txawm hais tias kev txhim kho thiab tsim cov nplaim hluav taws kub-shrinkable hauv Suav teb tsis ntev, txoj kev loj hlob sai. Tam sim no txoj kev txhim kho yog: multi-functional, ntau hom, thiab nws cov cheeb tsam daim ntawv thov tau dhau los ua ntau dua. Hauv luv, daim ntawv thov teb ntawm nplaim retardant tshav kub shrinkable raj tuaj yeem hais kom tob rau hauv lub teb chaws kev lag luam ntawm ntau yam kev lag luam, yog ib qho kev lag luam tshiab zoo heev.
