Zomatira zotentha zotentha (HMAs) ndi zomatira zotentha zotentha (HMPSAs) zakhala zikugwiritsidwa ntchito kwambiri popanga kwazaka zopitilira 40. Pafupifupi makampani onse kuphatikiza kulongedza, kulemba mabuku, matabwa, ukhondo, zomangamanga, magalimoto, zamagetsi, kupanga nsapato, nsalu zomangira, kusonkhanitsa zinthu, matepi ndi zolemba zimagwiritsa ntchito zomatira zotentha kwambiri. Kodi zida izi ndi ziti?

HMA ndi 100% zomatira zolimba zomwe zimagwiritsidwa ntchito posungunuka kuti zikwaniritse kutuluka ndi kunyowetsa. HMA imadalira kuziziritsa kuti ikhale yolimba kuti ipereke chomangira chothandizira. HMAs zambiri amakhala ngati thermoplastics pambuyo ntchito.

A HMPSA kuthamanga tcheru kusungunula otentha ndi HMA amene amakhalabe luso kupanga chomangira serviceable pansi pa kuunika kuwala kutentha firiji. Zomatira zomwe zimakhudzidwa ndi kupanikizika ndizovuta kwambiri ndipo zimakhala ndi nthawi yotseguka yopanda malire - kutanthauza kuti zimatha kulumikizana ndi gawo lina nthawi iliyonse. Ma HMPSA nthawi zambiri amagwiritsidwa ntchito popanga matepi osavuta kumva ndi zilembo.

HMA ikhoza kugawidwa m'mabanja awiri akuluakulu: ma HMA omwe sanapangidwe komanso opangidwa. Ma HMA omwe sanapangidwe amapangidwa mwadala ngati zomatira zomwe zingagwiritsidwe ntchito popanda kusinthidwa kwina ndi zida zina monga zomatira. Ma HMA ena omwe sanapangidwe ndi Poly-Esters (PET), Poly-Amides (PA), Poly-Urethanes (PU), ndi Poly-Olefins. Amapereka "hot tack" yoyamikirika kapena kuthekera kwa zomatira zotentha zosungunula kuti zigwirizanitse magawo pamodzi asanakhazikike kapena kukhazikika kapena kulimbitsa mphamvu pamene akutenthedwa ndikumangika pakutentha kokwera.

Ma HMA opangidwa amapangidwa ndi ma thermoplastic elastomers, tackifiers ndi zosakaniza zina. Mosiyana ndi ma HMA omwe sanapangidwe, ma elastomer oyambira a thermoplastic okha sakhala olimba kapena kutentha kwachipinda kapena kutentha kokwera. Ma elastomer atatu omwe amagwiritsidwa ntchito kwambiri ndi Styrenic Block Copolymers (SBCs), Ethylene Vinyl-Acetates (EVAs), ndi Amorphous Poly-Olefins (APOs). Ma elastomer a thermoplastic awa amasinthidwa ndi mitundu yosiyanasiyana ya ma tackifiers (achilengedwe komanso ma resin opangidwa) omwe amapanga machitidwe osiyanasiyana omatira malinga ndi zosowa za msika.

Ma HMA ambiri nthawi zambiri amatengera ma EVA. Zogulitsazi zimawonetsa nthawi yotseguka yayifupi (nthawi zambiri zosakwana masekondi 10) komanso kuthamanga kwachangu. Pokhapokha pang'ono kwambiri amatha kudziwika pa zomatira pamwamba kutentha firiji. Ma HMPSA makamaka amatengera ma SBC. Iwo ali okhazikika kwanthawi zonse kutentha kwa firiji ndipo amapereka mphamvu yolumikizana bwino pansi pa kukakamiza kwa chala chopepuka. Ma HMA opangidwa ndi APO amapereka nthawi yayitali yotseguka atagwiritsidwa ntchito ndikukhazikika kuchokera pagawo lawo losungunuka. Komabe; Sali otseguka kotheratu ndipo amataya matanki ambiri apansi akakhazikika. Makhalidwe apaderawa ndi othandiza kwambiri pamachitidwe omangirira omwe amafunikira nthawi yayitali yotseguka koma yotsika kwambiri pambuyo pomanga. Zotsalira zotsalira zapansi zidzapewa kuipitsidwa kwamtsogolo m'mphepete mwa madera omangirawo.

Kodi HMA yabwino ndi/kapena HMPSA ndi chiyani? Kunena zoona, palibe mankhwala angwiro ngati amenewa. Zomatira zonse ziyenera kupangidwa kapena kupangidwa molingana ndi zosowa zenizeni. Kodi timasankha bwanji HMA kapena HMPSA yoyenera pa zosowa zenizeni? Asanasankhe chinthu chabwino kwambiri chogwiritsira ntchito, zonse zomwe zimagwiritsidwa ntchito kumapeto ndi njira zogwiritsira ntchito ziyenera kufotokozedwa momveka bwino.

DeepMaterial ikhoza kupereka zomatira zotentha zosungunuka makonda. Mitundu yokhazikika ya zomatira zotentha zosungunuka zimatha kulumikiza magawo osiyanasiyana, kuphatikiza mapulasitiki ovuta kulumikiza. Zomatirazi zimatha kuthana ndi mitundu yonse ya zomangira zolimba kwambiri pamoyo. Zomatira zotentha zosungunuka ndizosankha bwino kwambiri pakukonza kothamanga kwambiri, kusiyanasiyana kolumikizana, kudzaza mipata yayikulu, mphamvu zoyambira mwachangu komanso kuchepa pang'ono.

Mitundu yokhazikika ya DeepMaterial zomatira zotentha zosungunuka zili ndi zabwino zambiri: nthawi yotseguka imayambira masekondi mpaka mphindi, safuna zosintha, kulimba kwa nthawi yayitali komanso kukana bwino kwa chinyezi, kukana mankhwala, kukana mafuta ndi kukana kutentha. Mitundu yogwira ntchito ya DeepMaterial ya zomatira zotentha zosungunuka sizisungunulira.
