Ziziphi iirensi ezisetyenziselwa iingubo ze-thermoplastic powder

Zintathu iiresin eziphambili ezisetyenziswa kuyo Thermoplastic powder ukutyabeka, iivinyls, iinayiloni kunye neepolyester. Ezi zixhobo zisetyenziselwa ezinye izicelo zoqhagamshelwano lokutya, izixhobo zendawo yokudlala, iinqwelo zokuthenga, iishelufu zesibhedlele kunye nezinye izicelo.

Imbalwa ye-thermoplastics inoluhlu olubanzi lweempawu zokubonakala, iimpawu zokusebenza kunye nokuzinza ezifunekayo kwizicelo ezisebenzisa i-thermoset powders.

Iipowder ze-Thermoplastic ziqhelekile zizixhobo ezinobunzima bemolekyuli ezifuna ubushushu obuphezulu ukuba bunyibilike kwaye buhambe. Ngokuqhelekileyo zisetyenziswa ngokusetyenziswa kwebhedi ene-fluidized kwaye iinxalenye zombini zifudumala kwangaphambili kwaye zifudunyezwe emva.

Uninzi lweengubo zepowder ze-thermoplastic zineepropati zokubambelela kwi-marginal ukwenzela ukuba i-substrate kufuneka iqhume kwaye iqhutywe ngaphambi kokusetyenziswa.

I-Thermoplastic powders i-fusible ngokusisigxina. Oku kuthetha ukuba, xa sele zitshisiwe, zinokuhlala zifudunyezwa kwaye ziphinde zisetyenziswe kwiimilo ezahlukeneyo njengeminqweno yomsebenzisi. Ngokwahlukileyo, i-thermoset powders, xa sele ishushu kwaye ibunjwe kwiimilo ezithile, ayinakuphinda ifudunyezwe ngaphandle kokutshisa okanye ukuphuka. Inkcazo yeekhemikhali yale ndlela yokuziphatha kukuba iimolekyuli ezikwi-thermoplastics zitsaleleka kancinci omnye komnye ngelixa kwi-thermoset ziqhagamshelwe ngamakhonkco.

Amandla kaVan der Waals atsala kwaye abambe iimolekyuli kunye. Ekubeni i-thermoplastics ichazwa ngamandla angenamandla e-van der Waals, amatsheyina emolekyuli enza i-thermoplastics awenza akwazi ukwanda aze abe bhetyebhetye. Kwelinye icala, xa i-thermosetting powders ishushusiwe, isabela ngokwekhemikhali, kwaye ikhompawundi entsha eyenziweyo ibonakala ngamandla anamandla e-van der Waals. Endaweni yokwenza amatyathanga amade, zenza iimolekyuli eziyikristale kwindalo, nto leyo eyenza ukuba imveliso ibe nzima ukuyiphinda isetyenziswe okanye iphinde inyibilike xa sele iphilisiwe.
