Kub yaj nplaum nplaum yog ib hom yas nplaum. Nyob rau hauv ib qho kev ntsuas kub, nws lub cev lub cev hloov pauv nrog qhov hloov pauv ntawm qhov kub thiab txias, thaum nws cov khoom siv tshuaj tsis hloov pauv. Nws yog non-toxic thiab tasteless. Nws yog ib puag ncig tus phooj ywg chemical khoom.
Vim tias cov khoom nws tus kheej yog khoom, nws yooj yim rau ntim, thauj thiab khaws cia, hnyav-dawb, tsis muaj kuab paug thiab tsis muaj tshuaj lom; Thiab qhov zoo ntawm cov txheej txheem tsim khoom yooj yim thiab kev sib raug zoo siab zog.

Pe ciab rau kub yaj nplaum muaj thermal poob qis, cov ntsiab lus roj tsawg thiab siab hardness.

Kub yaj nplaum nplaum muaj ntau thiab ntau ntau yam thiab siv. Nws tuaj yeem khi tawv, iav, hlau, ntoo, hnab yas, kev kho mob, textiles, thiab lwm yam. nws yog dav siv hauv kev tsim kho, textile, electronics, kho mob, tsheb thiab lwm yam lag luam.
Cov khoom ntawm kub yaj nplaum nplaum yog cov khoom siv hluavtaws. Cov khoom sib xws muaj xws li cov khoom hauv qab no: cov khoom tseem ceeb, tackifier, softener, muab tub lim, antioxidant thiab regulator.
Cov khoom tseem ceeb yeej plays lub luag hauj lwm txiav txim siab nyob rau hauv kev sib raug zoo zog, tshav kub tsis kam, toughness thiab nruab nrab kuj ntawm kub-melt nplaum. Nws feem ntau yog tsim los ntawm ib lossis ob peb lub siab molecular polymers. Softener ua rau kub yaj nplaum yooj yim los tsim thiab txheej txheem. Fillers feem ntau siv cov tshuaj inorganic uas tsis hnov ​​​​mob nrog cov khoom siv los ua kom cov viscosity ntawm colloids thiab txhim kho kev cuam tshuam thiab kev siv lub zog. Antioxidants ncua lub neej kev pab cuam thiab tshav kub tsis kam ntawm kub yaj nplaum.
Cov tsos thiab cov duab ntawm cov nplaum nplaum kub sib txawv raws li qhov sib txawv:
1. Kub yaj nplaum nplaum:
Cov nplaum nplaum yog ua los ntawm EVA ua cov khoom tseem ceeb, tackifier thiab lwm yam khoom. Nws muaj cov yam ntxwv ntawm kev ceev adhesion, siab zog, aging kuj, tsis muaj toxicity thiab zoo thermal stability. Nws tuaj yeem siv rau hauv cov ntoo, yas, ntim khoom thiab lwm yam khoom siv nplaum nplaum, thiab tuaj yeem siv dav hauv cov chaw tsim khoom thiab tsev neeg. Kub yaj kua nplaum nplaum feem ntau yog siv nrog kub yaj kua nplaum phom.

2. Cov khoom kub yaj:
Cov roj hmab kub yaj yog cov khoom nplaum yas. Nyob rau hauv ib tug tej yam kub thiab txias, lub cev lub cev ntawm kub yaj cov roj hmab hais hloov nrog cov kev hloov ntawm kub, thaum lub sij hawm cov tshuaj nyob rau hauv lub cev tsis hloov. Kub yaj roj hmab hais tsis muaj tshuaj lom thiab saj tsis qab. Lawv yog ib puag ncig tus phooj ywg kua nplaum khoom. Cov roj hmab kub yaj tuaj yeem siv rau hauv ntim hauv txhua qhov chaw ntawm lub neej. Kub yaj nplaum nplaum yog siv los yaj cov kub yaj nplaum los ntawm tshav kub hauv lub tshuab kub yaj nplaum, thiab cov kua nplaum tom qab melting ua kua. Cov nplaum kub yaj yog xa mus rau saum npoo ntawm cov khoom sib txuas los ntawm cov yeeb nkab kub-melt nplaum thiab cov phom kub-melt nplaum ntawm lub tshuab kub-melt nplaum, thiab kev sib txuas ua tiav tom qab cov nplaum kub yaj txias.
3. Kub yaj zaj duab xis:
Kub yaj nplaum zaj duab xis yog ib yam ntawm cov khoom siv zaj duab xis nrog cov ntawv tso tawm los yog tsis muaj daim ntawv tso tawm, uas tuaj yeem ua haujlwm tsis tu ncua lossis cuam tshuam. Nws tuaj yeem siv dav rau kev sib txuas txhua yam ntawm cov ntaub, ntawv, cov ntaub ntawv polymer thiab hlau.
Kub yaj nplaum zaj duab xis yuav muab faib ua thermoplastic thiab thermosetting raws li nws daim ntawv thov yam ntxwv. Nws muaj cov yam ntxwv hauv qab no:
(1) Nws muaj qhov zoo sib xws thiab sib koom ua ke thickness;
(2) Solvent-dawb, yooj yim rau txheej txheem;
(3) Zoo adhesion rau ntau yam khoom;
(4) Lub thickness yog 0.1-0.203mm thiab xim yog translucent / amber;
(5) Nws tuaj yeem raug xuas nrig ntaus rau hauv cov duab thiab qhov ntau thiab tsawg, thiab haum rau kev siv phau ntawv ntshiab lossis siv tsis siv neeg.
Daim ntawv thov khoom: nws tuaj yeem khi hlau, yas, ntawv, ntoo, ceramics, textile thiab lwm yam ntaub ntawv, thiab tseem tuaj yeem tau txais txiaj ntsig zoo ntawm cov khoom tsis sib xws.
4. Kub yaj siab rhiab nplaum nplaum:
Kub yaj siab-rhiab nplaum nplaum yog ib qho nplaum raws li thermoplastic polymer. Nws muaj ob yam ntxwv ntawm kub yaj thiab siab-rhiab heev. Nws tuaj yeem coated hauv lub xeev molten. Tom qab txias, nws tuaj yeem sib txuas sai sai los ntawm kev siv lub teeb siab. Nyob rau tib lub sijhawm, nws tsis tuaj yeem yooj yim ua paug rau saum npoo ntawm adherend.

Kev sib xyaw ua ke ntawm kub-melt siab-rhiab nplaum nplaum yog: polymer elastomer, xws li SIS, SBS, SEBS, SEPS, thiab lwm yam, nrog rau tackifier, plasticizer, muab tub lim thiab antioxidant. Nws yog tsuas yog thermoplastic elastomer, piv txwv li SBS thiab SIS thermoplastic elastomer. SBS, tseem hu ua thermoplastic styrene butadiene roj hmab, yog cov thermoplastic elastomer. SBS muaj zoo solubility thiab sib xws nrog ntau cov polymers. Ntxiv resin thiab tackifier tuaj yeem txo nws cov viscosity yaj. Nws yog qhov tsim nyog rau kev npaj kub-melt siab-rhiab nplaum nplaum. SIS yog ib qho thaiv copolymer ntawm styrene thiab isoprene. Nws muaj cov modulus tsawg, tsis tshua muaj kua viscosity thiab yaj viscosity thiab zoo processability. Vim tias SIS intermediate block polyisoprene muaj sab saw methyl hauv cov qauv, nws muaj kev sib koom ua ke zoo, zoo heev adhesion thiab zoo compatibility nrog rau lwm yam additives, SIS kub yaj siab rhiab nplaum nplaum muaj zoo pib adhesion dua SBS kub yaj siab rhiab nplaum nplaum.
Tackifying resin yog lwm qhov tseem ceeb ntawm cov nplaum nplaum tshwj tsis yog lub cev elastic. Nws lub luag haujlwm tseem ceeb yog muab lub siab-rhiab nplaum nplaum tsim nyog viscosity. Nws yog vim hais tias cov tackifying resin yog sib xyaw rau hauv cov roj hmab elastomer uas cov txheej txheem sib xyaw ua kom tsim nyog pib viscosity thiab adhesion rau saum npoo ntawm cov khoom sib txuas.
Feem ntau siv tackifiers tuaj yeem muab faib ua ob pawg:
Rosin series: rosin, rosin derivatives (hydrogenation, disproportionation, polymerization, esterification)
Ntuj cob terpene series: terpene resin (α－ Terpene β－ Terpene), terpene phenolic resin, aromatic resin , hydrogenated terpene resin.
