Impembelelo yoKhetho lweMathiriyeli kwiNtsebenzo yePlastiki ye-Extruder: Ukukhetha iResin eLungileyo

Intshayelelo

Ukukhethwa kwe-resin kunokuba nefuthe elibalulekileyo ekusebenzeni kwe-extruder yeplastiki. I-resin efanelekileyo inokunceda ukuphucula umgangatho wemveliso ekhutshiweyo, ukwandisa ukusebenza kakuhle kwemveliso, kunye nokunciphisa iindleko. Kule posi yebhlog, siza kuxoxa ngezinye zezinto ekufuneka ziqwalaselwe xa ukhetha i-resin ye-extruder yeplastiki.

Iimpahla zeMathiriyeli

Isinyathelo sokuqala ekukhetheni i-resin kukuqwalasela izinto eziphathekayo ezifunekayo kwisicelo. Ezinye zeempawu ezibalulekileyo zemathiriyeli ziquka:

• Amandla:Amandla e-resin aya kugqiba ukuba ubunzima obungakanani bemveliso ekhutshweyo inokuxhasa.
• Ukuqina:Ukuqina kwe-resin kuya kugqiba ukuba ingakanani imveliso ekhutshweyo iya kuphambuka phantsi komthwalo.
• Ukuchasa impembelelo:Ukuchasana kwempembelelo ye-resin kuya kugqiba ukuba imveliso ekhutshiweyo iya kumelana kangakanani nokuwiswa okanye ukubethwa.
• Ukumelana nobushushu:Ukumelana nokushisa kwe-resin kuya kugqiba ukuba imveliso ekhutshiweyo iya kumelana nobushushu.
• Ukunganyangeki ngamachiza:Ukunganyangeki kweekhemikhali ze-resin kuya kugqiba ukuba imveliso ekhutshiweyo iya kumelana kangakanani nokuvezwa kwimichiza.

Ukuqwalasela ukuqwalaselwa

Ukongeza kwiipropathi zezinto eziphathekayo, kubalulekile ukuqwalasela ukuqwalaselwa kwenkqubo xa ukhetha i-resin. Ezinye zezona zinto zibalulekileyo zokuqwalaselwa zibandakanya:

• Isalathisi sokunyibilika (MFI):I-MFI ngumlinganiselo wokuba i-resin ihamba ngokulula kangakanani xa inyibilika. I-MFI ephezulu iya kubangela amazinga okukhawuleza okukhupha.
• Viscosity:I-viscosity ye-resin ngumlinganiselo wendlela yokuxhathisa i-resin ukuhamba. I-viscosity ephantsi iya kubangela ukuqhutyelwa lula.
• Ubushushu bokutshintsha kweglasi (Tg):I-Tg liqondo lobushushu apho i-resin itshintsha ukusuka kwinto eqinileyo, ebhityileyo ukuya kwinto ethambileyo, eyirabha. Ubushushu bokulungisa kufuneka bube ngaphezulu kwe Tg ukuze intlaka ihambe kakuhle.

Ukuhambelana nezongezo

Ezinye iirasi ziyahambelana nezongezo ezinokuphucula ukusebenza kwazo. Ezinye izongezo eziqhelekileyo ziquka:

• Izigcwalisi: Iifayili zingasetyenziselwa ukuphucula amandla, ukuqina, kunye nokuzinza komda wemveliso ekhutshiweyo.
• Ukuqiniswa: Ukuqiniswa, njengemicu yeglasi okanye i-carbon fibers, ingasetyenziselwa ukuphucula ngakumbi amandla kunye nokuqina kwemveliso ekhutshweyo.
• Ii-Pigments: Ii-pigments zingasetyenziselwa ukongeza umbala kwimveliso ekhutshiweyo.
• I-UV stabilizers: Izizinzi ze-UV zingasetyenziselwa ukukhusela imveliso ekhutshiweyo kwimitha ye-UV.

Iindleko

Ixabiso le-resin yenye into ebalulekileyo ekufuneka iqwalaselwe. Iiresin zingohluka ngokwexabiso ukusuka kwiidola ezimbalwa ngeponti ukuya kumakhulu eedola ngeponti. Iindleko ze-resin ziya kuxhomekeka kwiipropati eziphathekayo, ukuqwalaselwa kokucubungula, kunye nokuhambelana nezongezo.

Ukuqukumbela

Ukukhethwa kwe-resin sisigqibo esibalulekileyo esinokuchaphazela kakhulu ukusebenza kwe-plastic extruder. Ngokuqwalasela ngononophelo iipropathi zezinto eziphathekayo, ukuqwalaselwa kokucubungula, ukuhambelana nezongezo, kunye neendleko, unokukhetha i-resin efanelekileyo kwisicelo sakho.
