Zomatira zotentha zosungunuka ndi mtundu wa zomatira zapulasitiki. Mkati mwa kutentha kwina, thupi lake limasintha ndi kusintha kwa kutentha, pamene mankhwala ake sasintha. Sichiwopsezo komanso chosakoma. Ndi chilengedwe wochezeka mankhwala mankhwala.
Chifukwa chakuti mankhwalawo ndi olimba, ndi abwino kulongedza, kuyendetsa ndi kusungirako, zopanda zosungunulira, zowonongeka komanso zopanda poizoni; Ndipo ubwino wa njira yosavuta kupanga ndi mkulu kugwirizana mphamvu.

Pe sera ya pe ya zomatira zotentha zosungunuka zimakhala ndi kuchepa kwamafuta ochepa, mafuta ochepa komanso kuuma kwakukulu.

Zomatira zotentha zosungunuka zimakhala ndi mitundu yambiri komanso ntchito. Ikhoza kumangiriza zikopa, magalasi, zitsulo, matabwa, mapulasitiki a katundu, chithandizo chamankhwala, nsalu, ndi zina zomwe zimagwiritsidwa ntchito pomanga, nsalu, zamagetsi, chithandizo chamankhwala, magalimoto ndi mafakitale ena.
Zigawo zonse za zomatira zotentha zimasungunuka ndi zinthu zopangidwa ndi organic. Zigawo zodziwika bwino zimaphatikizapo izi: zinthu zazikulu, tackifier, softener, filler, antioxidant ndi regulator.
Zinthu zazikuluzikulu zimagwira ntchito yofunika kwambiri pakulumikizana mwamphamvu, kukana kutentha, kulimba komanso kukana kwapakatikati kwa zomatira zotentha zosungunuka. Nthawi zambiri amapangidwa ndi ma polima amodzi kapena angapo apamwamba. Softener imapangitsa zomatira zotentha zosungunuka kukhala zosavuta kupanga ndi kukonza. Zodzaza nthawi zambiri zimagwiritsa ntchito zinthu zomwe sizigwirizana ndi zigawo zina kuti ziwonjezere kukhuthala kwa ma colloids ndikuwongolera kukana komanso mphamvu zamakina. Ma Antioxidants amakulitsa moyo wautumiki komanso kukana kutentha kwa zomatira zotentha zosungunuka.
Maonekedwe ndi mawonekedwe a zomatira zotentha zimasiyanasiyana malinga ndi zolinga zosiyanasiyana:
1. Ndodo yomatira yotentha yotentha:
Zomatira zolimba zimapangidwa ndi EVA monga chinthu chachikulu, tackifier ndi zigawo zina. Lili ndi makhalidwe omatira mofulumira, mphamvu zambiri, kukana kukalamba, kulibe kawopsedwe komanso kukhazikika kwabwino kwa kutentha. Itha kugwiritsidwa ntchito ngati nkhuni, pulasitiki, kulongedza ndi zolimba zina zomatira, ndipo zitha kugwiritsidwa ntchito kwambiri m'mafakitale ndi mabanja. Ndodo ya glue yotentha imagwiritsidwa ntchito ndi mfuti ya glue yotentha.

2. Hot Sungunulani particles:
Hot Sungunulani mphira particles ndi pulasitiki zomatira mankhwala. Mkati mwa kutentha kwina, mawonekedwe amtundu wa mphira wotentha amasintha ndi kusintha kwa kutentha, pamene katundu wa mankhwala amakhalabe osasintha. Hot Sungunulani mphira particles si poizoni ndi zoipa. Ndi zinthu zachilengedwe zokomera guluu. Tinthu tating'onoting'ono ta rabara totentha titha kugwiritsidwa ntchito pakuyika pamikhalidwe yonse yamoyo. Zomatira zomatira zotentha zimagwiritsidwa ntchito kusungunula zomatira zotentha zomwe zimasungunula kutentha mu makina omatira otentha, ndipo guluu likasungunuka limakhala madzi. Zomatira zotentha zotentha zimatumizidwa pamwamba pa chinthu chomangika kudzera mu chitoliro chomata chotenthetsera ndi mfuti yomatira yotentha yotentha ya makina omatira otenthetsera, ndipo kumangiriza kumatsirizika pambuyo poti zomatira zotentha zimakhazikika.
3. Firimu
yotentha yotentha
Hot Sungunulani zomatira filimu akhoza kugawidwa mu thermoplastic ndi thermosetting malinga ndi ntchito makhalidwe ake. Lili ndi makhalidwe awa:
(1) Lili ndi makulidwe abwino ogwirizana komanso ofanana;
(2) Zopanda zosungunulira, zosavuta kukonza;
(3) Kumamatira kwabwino kuzinthu zambiri;
(4) makulidwe ndi 0.1-0.203mm ndi mtundu translucent / amber;
(5) Ikhoza kukhomeredwa mu maonekedwe ndi kukula kwake, ndipo ndi yoyenera pamanja kapena ntchito zokha.
Kugwiritsa ntchito mankhwala: imatha kulumikiza zitsulo, pulasitiki, mapepala, matabwa, zoumba, nsalu ndi zipangizo zina, komanso kupeza zotsatira zabwino pamwamba pa zinthu zosagwirizana.
4.
Zomatira zomatira zomata ndi zomatira zochokera ku polima wa thermoplastic. Ili ndi mawonekedwe apawiri a kusungunula kotentha komanso kuvutikira. Ikhoza kuphimbidwa ngati yosungunuka. Pambuyo pozizira, imatha kumangirizidwa mwachangu pogwiritsa ntchito mphamvu ya kuwala. Panthawi imodzimodziyo, sichikhoza kuipitsa mosavuta pamwamba pa adherend.

Zomwe zimapangidwira zomatira zomwe zimatentha kwambiri ndi: polymer elastomer, monga SIS, SBS, SEBS, SEPS, etc., komanso tackifier, plasticizer, filler ndi antioxidant. Makamaka ndi thermoplastic elastomer, mwachitsanzo SBS ndi SIS thermoplastic elastomer. SBS, yomwe imadziwikanso kuti thermoplastic styrene butadiene rabara, ndi thermoplastic elastomer. SBS ili ndi kusungunuka kwabwino ndipo imagwirizana ndi ma polima ambiri. Kuonjezera utomoni ndi tackifier kungachepetse kusungunuka kwake kusungunuka. Ndizoyenera kwambiri pokonzekera zomatira zotentha-zotentha zosungunuka. SIS ndi block copolymer ya styrene ndi isoprene. Iwo ali otsika modulus, otsika kukhuthala kwa njira ndi kusungunuka mamasukidwe akayendedwe ndi processability wabwino. Chifukwa SIS yapakatikati ya block polyisoprene ili ndi unyolo wam'mbali wa methyl mu kapangidwe kake, imakhala ndi kulumikizana kwabwino, kumamatira kwabwino komanso kumagwirizana bwino ndi zowonjezera zina, zomatira zomatira za SBS zotentha zotentha zimakhala ndi zomatira zoyambira bwino kuposa zomatira za SBS zotentha zosungunuka.
Tackifying utomoni ndi gawo lina lofunika la zomatira-zomvera kupsinjika kupatula thupi lalikulu lotanuka. ntchito yake yaikulu ndi kupatsa kuthamanga-tcheru zomatira zofunika kukhuthala. Ndi chifukwa tackifying utomoni wothira mphira elastomer kuti kusanganikirana dongosolo limatulutsa zofunika kukhuthala koyamba ndi kumamatira pamwamba pa zinthu zomangira.
Ma tackifiers omwe amagwiritsidwa ntchito nthawi zambiri amatha kugawidwa m'magulu awiri
: rosin, zotumphukira za rosin (hydrogenation, disproportionation, polymerization, esterification)
mndandanda wachilengedwe wa resin terpene: terpene resin (α－ Terpene β- Terpene), terpene phenolic resin, zonunkhira zosinthidwa terpene , hydrogenated terpene utomoni.
