Iingxowa zokupakisha zeplastiki zenziwe nge-polypropylene (PP) njengeyona nto iphambili ekrwada, ekhutshiweyo, itsalwa ngesinyithi, ilukiweyo, ilukiwe, kwaye yenziwe kwiingxowa zokupakisha.
I-PP yiplastiki ye-thermosetting ecacileyo, ene-semi-crystalline enokuqina okuphezulu, iipropathi ezilungileyo zokugquma, ukufunxa kwamanzi aphantsi, ubushushu obuphezulu be-ambient, ukuxinana okusezantsi, kunye nobushushu beglasi ephezulu.Yeyona mathiriyeli iphambili yokwenza iingxowa zokupakisha.Izinto zokuhluza ezilungisiweyo zihlala zibandakanya iifiber zeglasi, izixhobo zokuzalisa iiminerali, irabha ye-thermoplastic, kunye nokunye.
Umda wokusetyenziswa kweengxowa zokupakisha zeplastiki ubanzi kakhulu.Kweli nqanaba, izicelo eziphambili zeengxowa zokupakisha zeplastiki kukupakishwa kwangaphandle kweemveliso zezolimo, ukupakishwa kwangaphandle kweengxowa ezilukiweyo zeplastiki, izinto zokupakisha ukutya, ubunjineli bejoloji, ukuthutha ukhenketho lweeholide, ukulwa nezikhukhula kunye nezinto ezingxamisekileyo, njl. iintlobo eziphambili zeengxowa zokupakisha: iingxowa zokupakisha zeplastiki (iingxowa zokupakisha ezingenafilimu), iingxowa zokupakisha zeplastiki ezihlanganisiweyo kunye neengxowa ezahlukeneyo ezilukiweyo.Inkqubo yemveliso yeengxowa zokupakisha zeplastiki yile: iingxowa ezilukiweyo ziba ziingxowa zokupakisha emva kokupakishwa kunye nokushicilela, ukusika i-laser kunye nokuthunga.
Ngokuxhomekeke kumatshini kunye nezixhobo ezisetyenzisiweyo, inokusikwa ngelaser ize iprintwe, okanye iprintwe kwaye emva koko isikwe laser.Umatshini wokuthunga we-laser ozenzekelayo unokuqhubeka nenkqubo yokupakisha, ukusika i-laser, umatshini wokuthunga, njl., kwaye unokwenziwa kwiipokotho zevalve, iipokotho ezisezantsi, njl. ibhegi inokwenziwa.Inkqubo yemveliso yeengxowa zokupakisha zeplastiki ezihlanganisiweyo kukufaka iingxowa ezilukiweyo, amatye adibeneyo okanye iifilimu zoxolelwaniso okanye zokugquma.Imiqulu efunyenweyo okanye amaphepha kunye nemiqulu inokusikwa ngelaser, ipakishwe kwaye iprintwe kwaye ithungwe ngotyando ukwenza iingxowa ezisezantsi zomthungo jikelele.Basenokuvula imingxunya, i-edge crimping, ukusika i-laser, ukupakisha ukuprinta, ukuthungwa ngotyando kunye neengxowa ezilukiweyo zeplastiki.Iphepha elifunyenweyo linokudityaniswa ngomthungo, ukuprintwa kwephakheji, ukusika i-laser, i-lid bonding kunye nebhegi yokunamathisela.Inokuthi idityaniswe, ibekwe, ihlulwe, yenziwe kwiishedi zomthi kunye nee-geotextiles ezingalukwanga.I-Flat looms ingaba yimveliso ephindaphindiweyo okanye engapheliyo kunye nokuveliswa, i-geotextiles engalukiweyo, njl.
Izalathisi zokusebenza zenkqubo yokuvelisa umatshini wokuzoba ngocingo lweplastiki zahlulwe ikakhulu ngokweendidi ezine:
1. Ixabiso lesalathiso sokwenziwa komzimba.Kukho ubukhulu becala iimpazamo zeyunithi ezinje ngokuqhawuka kwamandla, amandla okuqhawuka, amandla okuqina, isantya se-angular, kunye nokuxinana;
2. Amaxabiso esalathiso sezinto eziguqulwe ngokwekhemikhali.Ikakhulu ibandakanya ukudibanisa izinto ezilungisiweyo, ukulungiselela ukuxuba, ukongeza umlinganiselo wemodyuli, kunye nomlinganiselo wenkunkuma ehlaziyiweyo yesichumisi sekhompawundi yegranular;
3. Ixabiso lesalathiso sokunyamezelwa kweDimensional.Iquka ubukhulu becala ubukhulu bomatshini wokuzoba ucingo lweplastiki kunye nobubanzi bocingo olusicaba.
4. Iimpawu eziphathekayo ixabiso lesalathisi se-rheological.Kukho ubukhulu becala umlinganiselo wokuqhekeka kwemisonto, umlinganiselo wokunyuka kwamaxabiso, umlinganiselo oyidrafti kunye nomlinganiselo wokushwabana;
Ithekhnoloji yokucwangcisa ingxowa enemigca Uxinzelelo oluphezulu lwepolyethylene impahla ifudunyezwa yi-extruder, inyibilike kwaye ikhutshwe kakuhle;
Cinezela iplastiki emise okomgqomo kwifilimu yeplastiki emile okwebhari;ngena ukunciphisa uthuli oluvuthelayo kwaye ubangele iibhubhu zetyhubhu;
I-herringbone-shaped hair straightening splint ipholile kwaye ibunjwe yindandatho yomoya opholileyo, kwaye i-traction iziswe ekuguquleni;
I-roller ye-drive system itsalwa kwi-winding roller ngokusebenzisa i-belt belt roller;
Ekugqibeleni, ukusika kwe-laser kuqhutyelwa, isikhwama se-lining siveliswa yinkqubo eshushu-encibilikayo, kwaye ekugqibeleni isiqhamo sifakwe.
Ipolypropylene ecocekileyo ayinakuhlangabezana neemfuno zoomatshini bokuzoba ngocingo lweplastiki, kodwa ikwafuna ukongeza ipesenti ethile ye-polyethylene, i-calcium bicarbonate kunye ne-masterbatch yombala.Ukongeza inani elincinci le-polyethylene ngexesha lenkqubo yonke ye-extrusion inokunciphisa i-viscosity kunye nesantya sokunyibilika kokuhamba kwezinto, ukuphucula umbane, ukuphucula i-ductility kunye nokuguquguquka komatshini wokuzoba ngocingo lweplastiki kunye neengxowa zokupakisha zeplastiki, ugcine amandla athile okuqina, kwaye ukuphucula i-polypropylene ultra-low ubushushu umonakalo.
Izongezo ze-polypropylene eziphuculweyo zinokunciphisa ubushushu kunye noxinzelelo lokusebenza kwindawo yokuvelisa kunye nokucubungula.Ukuphucula ukuhamba kwedatha kunye nokubambelela, phucula amandla okuqina.Ukongezwa kwe-calcium bicarbonate kunokutshintsha iintsilelo zokungafihli ngokupheleleyo kunye nokungafihli.Ekunciphiseni ukunwebeka, yonke le nkqubo iyingozi kwi-electrostatic induction njengoko iyingozi kwi-friction, iphucula ukunamathela kwe-inki yokuprinta ukupakishwa kunye nokushicilela iilogo zentengiso, ukunciphisa ukuqokelela kwendalo kunye nokulawula iindleko zeemveliso ezigqityiweyo ngexesha lokugcinwa.
