I-Polystyrene (PS) imathiriyeli lukhetho oludumileyo kwi-carrier tape ekrwada ngenxa yeempawu zayo ezizodwa kunye nokwakheka. Kule nqaku, siza kujonga ngakumbi kwiipropati ze-PS kwaye sixoxe ngendlela ezichaphazela ngayo inkqubo yokubumba.
Izinto ze-PS yipolymer ye-thermoplastic esetyenziswa kumashishini ahlukeneyo afana nokupakishwa, i-elektroniki kunye neemoto. Kwimveliso ye-tape ye-carrier lukhetho oluhle kakhulu ngenxa yezoqoqosho, ukuqina kunye nokumelana nokushisa.
Xa usebenzisa izinto ze-PS njenge-carrier tape ekrwada, kuyimfuneko ukuqonda iimpawu zayo. Okokuqala, i-PS i-polymer e-amorphous, oku kuthetha ukuba ayinayo i-crystalline ebonakalayo. Olu phawu luchaphazela iimpawu zalo zomatshini kunye ne-thermal, oko kukuthi ukuqina, ukunyanzeliswa, ukungabonakali kunye nokumelana nokushisa.
Indibaniselwano eyodwa yeepropathi zezinto ze-PS zibenza balungele ishishini lombane. Ngokukodwa, ukuchasana komswakama kuqinisekisa ukukhuselwa kwamacandelo e-elektroniki ngexesha lokuthutha okanye ukugcinwa. Yiyo loo nto imathiriyeli ye-PS ilukhetho oludumileyo lweteyiphu yokuthwala impahla ekrwada.
Enye inkalo ebalulekileyo yezinto ze-PS kukubunjwa kwayo. Ngombulelo kwi-viscosity yayo ephantsi yokunyibilika, i-PS inokwakheka okugqwesileyo, ivumela ukugqitywa komgangatho ophezulu kunye namaxesha okusebenza ngokufanelekileyo xa ivelisa i-carrier tape imathiriyeli ekrwada.
PS ukubumba ukusebenza
1. Izinto ze-amorphous zine-absorption ephantsi yomswakama, ayifuni ukuba yomiswe ngokupheleleyo, kwaye akulula ukubola, kodwa ine-coefficient enkulu yokwandisa i-thermal kwaye ixhomekeke kuxinzelelo lwangaphakathi. Inomanzi kwaye inokubunjwa ngesikrufu okanye umatshini wokutofa weplunger.
2. Kufanelekile ukusebenzisa ubushushu bezinto eziphezulu, ubushushu obuphezulu bokungunda, kunye noxinzelelo oluphantsi lwesitofu. Ukwandisa ixesha lokutofa kunenzuzo ekunciphiseni uxinzelelo lwangaphakathi kunye nokuthintela i-shrinkage cavity kunye ne-deformation.
3. Iindidi ezahlukeneyo zamasango zingasetyenziswa, kwaye isango lidibaniswe nenxalenye yeplastiki kwi-arc ukuphepha umonakalo kwinxalenye yeplastiki ngexesha lesango. I-slope ye-demoulding inkulu, kwaye i-ejection ifana. Ubunzima bodonga lwenxalenye yeplastiki bufanayo, kwaye akukho kufakwa kangangoko kunokwenzeka, njenge-Insets kufuneka ifudunyezwe.
Ukushwankathela, imathiriyeli ye-PS lukhetho oluhle kakhulu lwezixhobo zeteyiphu ekrwada ngenxa yeempawu zayo ezizodwa kunye nokwakheka. Njengepolymer ye-thermoplastic, i-PS inoqoqosho, iqinile kwaye iyamelana nobushushu. Ukongeza, ukumelana nokufuma kwayo kuyenza ilungele ukukhusela izinto ze-elektroniki ngexesha lothutho kunye nokugcinwa.
Ukuqonda iimpawu ze-PS kunye neempembelelo zabo kwinkqubo yokuqulunqa kubalulekile ekuphuculeni imveliso ye-carrier tape. Ngokukhetha izixhobo ze-premium ze-PS, sinokuvelisa iiteyipu zomthwali zomgangatho olungileyo kunye nokusebenza kakuhle, ukuqinisekisa impumelelo yayo nayiphi na imveliso yesixhobo sombane.
