Xaiv cov lus qhia kub uas haum rau kub yaj yaj yuav tsum xav txog lwm cov fibers, cov cua sov ua haujlwm hauv cov ntaub, thiab cov khoom siv kawg, thiab cov khoom kawg ntawm cov khoom siv. Cov ntsiab cai hauv qab no thiab cov ntaub ntawv tuaj yeem coj cov kev xaiv:
1. Melting point yuav tsum yog txog 40 degree rau 60 degree qis dua tsis muaj melting fibers
Txhawm rau kom ntseeg tau tias kub yaj cov yarn melts thiab cov nyiaj sib tsoo thaum lub sijhawm tshav kub lossis kev sib koom tes tsis muaj kev cuam tshuam txog 40 qib qis dua li ntawm cov xov paj tsis zoo. Piv txwv li, yog hais tias lub ntsiab lus melting ntawm polyester xov yog nyob ib ncig ntawm 250 degree, lub kub yaj, lub kub yaj yuav tsum muaj nyob rau hauv cov ntau ntawm 100 degree mus txog 165 degree.
2. Xaiv cov ntsiab lus melting raws li kev ua thiab kev ntsuas kub
Tsawg melting taw tes kub yaj xov (100 degree -130 degree):Haum rau cov khoom siv cua sov, ua haujlwm rau kev sib koom tes ntawm cov khoom kub tsawg, txuag lub zog, thiab tsim nyog rau kev ntim khoom, cov khoom siv textile, thiab tsawg-kub.
Nruab nrab melting taw tes kub yaj xov (130 degree -160 degree):Haum rau cov ntawv thov kev lag luam dav dav, muaj zog sib txuas thiab lub cua sov ua kom zoo, siv rau hauv cov khaub ncaws, cov ntawv nyeem hauv tsev, thiab cov khoom siv tsheb.
Siab melting taw tes kub yaj xov paj (saum toj 160 degree):Haum rau kev kub-ib puag ncig thiab cov khoom uas yuav tsum muaj kev ruaj khov, xws li cov khoom lag luam hauv tsheb thiab sab nraum zoov, muaj peev xwm los nrog kev ua haujlwm siab dua thiab kev pabcuam kub.
3. Kev txiav txim siab ua tau zoo thiab melt viscosity
Yog hais tias lub ntsiab lus melting yog tsawg heev, lub kub yaj tau paj tej zaum yuav ua ntej yaj thaum siv lossis siv, ua rau kev ua neeg tsis zoo. Yog tias dhau lawm, nws yuav tsis yaj yaj txaus rau kev sib tw tau zoo. Lub suab viscosity me me tseem cuam tshuam cov txiaj ntsig zoo: Ntau dua viscosity favors muaj zog sib txuas txheej txheej, thaum txo qis viscosity suits cov ntaub ntawv finer.
4. Zam kev siv cov ntaub ntawv nrog cov ntsiab lus zoo nkauj tab sis tsis muaj kev ruaj khov
Piv txwv li, polypropylene Kub Kub Kub Kub Suab Xov Xwm Muaj qhov taw tes zoo heev tab sis ua rau nws tsis pom zoo ib puag ncig thiab feem ntau tsis pom zoo.
5. Txheeb cov ntsiab lus melting rau cov khoom siv zaum kawg ntawm cov khoom lag luam
Yog tias cov khoom lag luam yuav raug rau qhov kub (xws li cov khoom siv hauv tsheb lossis cov khoom lag luam kub), xaiv kub yaj cov xov paj nrog rau kom ntseeg tau lub zog ua kom meej thiab kub ua kom tsis taus. Txog cov khoom yuav tsum tau softness thiab tsawg-ua, qis melting point kub cov xov paj yog qhov zoo dua.
Cov Ntsiab Lus Tshaj Tawm Rau Meltings Taw Kev Xaiv
| Melting taw tes ntau (degree) | Cov ntawv thov uas tsim nyog | Cov yam ntxwv thiab cov txiaj ntsig |
|---|---|---|
| 100–130 | Cov ntaub ntawv kub tiv thaiv cov ntaub ntawv, qis-temp ua | Kev Ua Kom Yooj Yim, Zog-Txuag, Haum rau Ntim thiab Textile Composites |
| 130–160 | Kev lag luam Industrial Siv, Apparel, tsev ntawv | Lub zog sib haum xeeb, muaj hluav taws kub tiv thaiv |
| 160 | High-temp ib puag ncig, Automotive, Sab nraum zoov iav | High Thaum tshav kub kub kuj, muaj siab ruaj khov |
Nco ntsoov tias kub yaj xov paj yog txog 40-60 degree qis dua li cov khoom kub thiab tsis sib haum thaum lav zoo sib raug zoo thiab kev ua tau zoo.
