Kodi kusankha guluu pulasitiki

Zosiyanasiyana pulasitiki ambiri, koma iwo onse kugwa m'magulu awiri: thermoplastics ndi thermosets.

Choncho, chifukwa apamwamba kukonza mankhwala pulasitiki tiyenera kudziwa zimene mtundu wa pulasitiki iwo amapangidwa, zikuthandizani kudziwa zimene zomatira kumata pulasitiki wa gulu lina. Ngakhale looneka wopepuka kwenikweni ndi zidule awo. Mwachitsanzo, zidole pulasitiki akhoza anakonza ntchito ochiritsira soldering chitsulo, koma karbalitovoy chotayilamo fodya bwino ntchito zomatira kwa pulasitiki mtundu BF-2. Ine akamufunsirire kuganizira magulu onse zambiri, kuti adziwe subtleties onse kogwirizana zikukhudza mbali.

Kukonza ndi gluing wa thermosets

Zinthu izi mtundu wa pulasitiki sangathe kufewetsa, kusungunula ndi kukonzanso mawonekedwe, ndi ngati chinthu wasweka, likhoza ulimbo. Ku mapulasitiki zoterozo mbale, mitsuko mafutawo, mabatani, milandu kwa mafoni ndi makamera, mwake ndi mapulagi. Onse a zinthu izi mosavuta kuswa kapena osokoneza ndi kugwa, ndipo iwo ayenera kukonza zomatira kwa pulasitiki mtundu BF-2 ndi BF-4, komanso nitrocellulose, polyvinyl mankhwala enaake ndi polyvinyl nthochi zomatira.

Kogwirizana ikuchitika mu magawo angapo:

1. Wovulala mosamala kutsukidwa ku fumbi ndi uve, ndipo onetsetsani kuti degrease. Chifukwa chaichi mfundo wosweka bwino nadzatsuka ndi madzi otentha ndi sopo.
2. Pa mosamala zouma ndi zomatira ntchito pamwamba wosanjikiza zoonda ndi zouma izo kuti sadzakhala n'kudziphatika kwa zala.
3. The chachiwiri zomatira wosanjikiza komanso umagwiritsidwa ntchito pa pamalo ndi kuloledwa kuima kwa mphindi 1-2, kenako mbali amaphatikizidwa ndi kuikidwa pansi atolankhani.
4. Kuyanika ndondomeko kumatenga masiku 3-4.

Kukonza ndi mgwirizano wa thermoplastics

Mapulasitiki gulu thermoplastics mosavuta anasintha chifukwa cha kutentha ndipo akhoza adzasungunuka pansi pa zochita mankhwala ena. pulasitiki Izi ntchito popanga zolembera malo, mbale sopo, zisa, mafelemu choonetsedwa ndi zidole ana. Poyamba, zinthu izi zinali za kuyaka pulasitiki yokhuthala, koma tsopano chinasiya anthu omwe si flammable mapadi nthochi. Ndipo iye ndi pulasitiki ena sungunuka acetone. Zomatira wa mtundu uwu mukhoza kupanga pulasitiki yekha, ichi Pakufunika zikugwira ntchito pa mtundu anakhumba pulasitiki zosungunulira (2 mbali) ndi tchipisi yokhuthala (1 gawo). zosakaniza ali osokonezeka ndi kusungidwa mu chidebe ndi chivindikiro mwamphamvu.

Ogwirizana thermoplastic wosiyana thermosets, akhoza akuyendera njira zingapo:

njira 1

mbali akanadulidwa lubricating amasintha zosungunulira pulasitiki, ndipo dikirani mpaka kugawanika m'mbali adzakhala yomata, ndiye kuwonjezera zinthu ndi kuika pansi atolankhani kumaliza oipa.

njira 2

Pakuti gluing ntchito nitrocellulose zomatira kwa pulasitiki mtundu "Mars", "C-1" ndi "MC-1".

3 Way

M'mbali kuti angongole ali usavutike pamwamba kuwala umagwiritsidwa thereto kapena achitsulo, inatuluka anasintha mbali m'mphepete ogwirizana. Pamene Kutentha m'pofunika kuteteza moto, kuti msoko sanali mdima.

Choncho, kukonza chinthu kumatenga nthawi yaitali ndipo sanataye mawonekedwe, m'pofunika kusankha zomatira zabwino mtundu wa pulasitiki. Ndipotu yekha bwino anasankha zomatira adzapereka kugwirizana odalirika.
