Kafukufuku wa akupanga pulasitiki wowotcherera zida kapangidwe-I

Popanga zinthu zamapulasitiki, ukadaulo wowotcherera akupanga ukhoza kusindikiza zinthu zapulasitiki mwachangu komanso moyenera.Kupatula apo, pakusindikiza, sikofunikira kukhala ndi zida zapulasitiki zotenthetsera zakunja kapena osafunikira flux, mphamvu yowotcherera ndiyabwino kwambiri komanso mphamvu yowotcherera ndiyokwera kwambiri.Pa akupanga kuwotcherera luso mu ntchito ndondomeko, mbali ya mtengo wotsika ndi mkulu chitetezo chimapangitsanso chimagwiritsidwa ntchito mu mankhwala pulasitiki makina, makampani stationery, zodzoladzola makampani, zidole makampani, zamagetsi makampani.

1. Akupanga pulasitiki kuwotcherera luso ndi makhalidwe ake

1. 1 Akupanga pulasitiki kuwotcherera luso

Akupanga pulasitiki kuwotcherera luso ndi kuwotcherera mankhwala pulasitiki pamodzi kudzera akupanga kugwedera mfundo.Pamene akupanga yoweyula ntchito kuwotcherera pulasitiki welds, mikangano zidzachitika pakati pa mamolekyu mu akupanga yoweyula ndi kukhudzana pamwamba pa mankhwala pulasitiki, ndiyeno kutentha kwa kuwotcherera pa pulasitiki kuwotcherera pamwamba mwamsanga kufika kusungunuka kwa pulasitiki.Panthawiyi, kusungunuka kwa ma welds awiri apulasitiki kumayenda pamodzi.Pamene mamolekyu mu akupanga yoweyula amasiya kunjenjemera, The pulasitiki Sungunulani ndi pansi mavuto ndipo mwamsanga solidifies ndi crystallizes, kupanga weld ngakhale.Mphamvu ya kuwotcherera mfundo ndi pafupi ndi zopangira.Pofuna kuwotcherera pulasitiki makina welds pamodzi, m'pofunika kuonetsetsa kuti kutentha kwaiye ndi akupanga yoweyula akhoza kuchitika m'dera kuwotcherera, ndi lolingana mphamvu kalozera dongosolo ayenera kugwiritsidwa ntchito kusamutsa ndi kutsogolera kutentha kwaiye akupanga yoweyula, ndi mphamvu yowongolera mphamvu imatchedwanso mawonekedwe a waya wowotcherera.

1.2 Makhalidwe aukadaulo akupanga pulasitiki kuwotcherera

Akupanga pulasitiki kuwotcherera luso ndi oyenera thermoplastics okha, ndi zipangizo zina si oyenera ntchito.chifukwa chosankha thermoplastics ndikuti mankhwala ndi thupi la thermoplastics amakhalabe osasintha pamene amasungunuka ndikuchiritsidwa.Thermoplastics akhoza kugawidwa mu crystalline ndi amorphous malinga ndi katundu wawo.Pakati pawo, malo osungunuka a pulasitiki a crystalline ndi odziwikiratu, ndipo mamolekyu ake amkati adzakonzedwa motsatira malamulo oyenerera pamene akuchiritsa kupanga kristalo dera.
