Hom thiab siv ntau ntawm cov khoom ib puag ncig lim ntaub
Coob tus neeg tseem tsis tau paub ntau txog cov ntaub thaiv ib puag ncig kev tiv thaiv. Hnub no kuv yuav hais me ntsis, vam tias yuav pab tau koj
Hom thiab kev siv ntawm cov ntaub lim
Lub taub lim ntaub tiv taus cov kua qaub thiab tsis muaj zog alkali. Hnav tsis kam, corrosion tsis kam thiab lwm yam khoom. Ntawm lawv, qhov kub tsis kam ntawm polyester fiber yog feem ntau 130 --- 150 ° C. Tom ntej no, cov ntaub ntawv yuav qhia koj txog hom thiab kev siv ntawm cov ntawv lim.
Polyester lim ntaub
Muab faib rau cov ntaub lim polyester.
Thaum tshav kub kub ua hauj: 120 ℃, tawg elongation (%): 20-50, tawg lub zog (g / d): 438, melting point (℃): 238 · 240, melting point (℃): 255-260. Lub zog nqus tshwj xeeb: 1.38. Kev ua haujlwm lim: cov khoom siv raw qauv ntawm polyester staple fiber lim daim ntaub yog luv thiab wooly, thiab cov ntaub npuag yog ntom ntom, nrog zoo particle khaws cia, tab sis tsis zoo tev thiab huab cua permeability. Lub zog thiab hnav tsis kam, kev tiv thaiv dej tsis zoo dua li ntawm polyester filament lim ntaub.
Siv: tshuaj, qab zib, zaub mov, tshuaj, metallurgy, kev lag luam lim xovxwm, centrifuge, thiab lwm yam.
Polyester ntsiabteeb lim ntaub cov khoom cov khoom siv: acid tsis kam, tsis muaj zog alkali tsis kam. Nws muaj cov cwj pwm zoo tiv thaiv, tiv taus corrosion thiab cov khoom rov qab, thiab hluav taws xob tsis zoo. Qhov kub tsis kam ntawm polyester fiber yog feem ntau 130 --- 150 ℃. Cov khoom no muaj qhov zoo ntawm cov ntaub ntawv lim zoo tib yam, thiab muaj zoo heev abrasion tsis kam. Nws muaj qhov ua tau zoo ntawm tus nqi thiab dhau los ua tus loj ntawm cov ntaub ntawv lim. Ntau yam. Thaum tshav kub kub ua hauj: 120 ℃, tawg elongation (%): 20-50, tawg lub zog (g / d): 438, cov kis ua kom tawv nqaij (℃): 238-240, melting point (℃): 255-260. Lub zog nqus tshwj xeeb: 1.38. Kev ua haujlwm lim: lub polyester lim ntaub ntawm lub cev muaj qhov chaw du zoo, txhim kho zoo kuj, thiab lub zog siab. Tom qab ntswj, nws muaj lub zog dua thiab zoo dua qub tiv thaiv, yog li cov ntaub muaj cov huab cua zoo permeability, dej nqus sai thiab ntxuav yooj yim. Siv: tshuaj, khoom noj, tshuaj lom neeg, metallurgy, kev lag luam lim xovxwm, centrifuge lim daim ntaub, thiab lwm yam.
Nylon lim ntaub
Nylon fiber muaj lub zog loj, lub zog yog 4-5.3 Cndtex. Elongation tus nqi yog 18% -45%. Ntawm 10% elongation, tus resilience tus nqi yog siab dua 90%. Lub zog ntawm nylon yog tus muaj zog ntawm cov fibers. Raws li kev ntsuas, qhov ua puas ntawm cov nylon fiber yog 10 zaug ntawm cov paj rwb fiber ntau thiab 50 zaug ntawm viscose. Kev txhim kho zoo tsis kam, yog li nias ua ke nrog cov roj hmab yog qhov khoom siv zoo rau kev ua lub log tsheb. Nylon fiber yog cov tshuaj tiv thaiv kom muaj zog alkali thiab tsis muaj zog acid. Tom qab 16 teev ntawm kev kho nrog NaoH (10%) ntawm 95 ℃, lub zog poob yog qhov tsis txaus ntseeg, tab sis nylon tsis yog lub teeb nrawm, yooj yim hloov xim thiab ua nkig, yog li cov nylon ntaub yuav tsum tsis txhob raug rau lub hnub ci ntev. Nylon 66 tsis tuaj yeem siv rau hauv cov chaw tsim tshuaj thiab khoom noj vim tias nws yog lom thiab ua rau tib neeg muaj mob.
Siv: roj hmab, ceramics, tshuaj lag luam, khoom noj khoom haus, metallurgy, thiab lwm yam Khoom siv qauv: 30l, 407, 663, 17-2, 17-7.
Polypropylene lim ntaub
Kev faib tawm cov ntaub lim: polypropylene staple fiber lim ntaub; polypropylene ntev fiber ntau daim ntaub.
Kev ua haujlwm lim: polypropylene staple fiber, luv fiber, spun xov xov xov plaub hau; polypropylene ntev fiber, fiber ntau ntev, cov xov paj tsim yog tus du, yog li daim ntaub kev lag luam ua los ntawm polypropylene staple fiber, daim ntaub saum npoo yog plaub, hmoov lim thiab siab lub txiaj ntsig zoo dua li cov fiber ntev. Kev lag luam daim ntaub ua los ntawm polypropylene ntev fiber muaj qhov chaw du thiab huab cua zoo permeability.
Vinylon cov ntaub lim dej
Kev Ua Tau Zoo: Lub npe tshuaj ntawm lub vinylon lim daim ntaub yog polyvinyl cawv. Nws lub zog yog qis dua li ntawm polyester, thiab nws lub zog tsuas yog 3.52-5.72 Cndtex. Lub elongation thaum so yog 12% ～ 25%. Kev ua tsis tau zoo, tsis zoo rau cov ntaub ua kom zoo, kev txhim kho kom zoo, thiab cov khoom siv tau ntev li 1-2 zaug ntawm cov paj rwb ntshiab. Tab sis muaj qhov kom zoo dua uas nws tuaj yeem tiv thaiv qhov kev txiav txim ntawm muaj zog alkali, thiab muaj hygroscopicity zoo thiab yooj yim los ua ke nrog roj hmab. Nws yog cov khoom siv zoo rau kev lag luam roj hmab. Nws qhov tsis zoo yog tias qhov kub tsis txias, thiab qhov kub nws yog 100 ℃. Kev ntsws, tsis yog acid tiv taus. Siv: Siv rau cov tuam ntxhab nrog alkalinity muaj zog thiab kev lag luam roj hmab. Tus qauv khoom: 295—1, 295—102, 295—104, 295—105, 295—107, 295—114, 295—1 (A)
