1. Intshayelelo kwiingxowa ezilukiweyo kunye nobuchwepheshe bazo bokucutshungulwa
Iingxowa zeplastiki ezilukiweyo zenziwe ngokuyintloko nge-polypropylene (PP), eziveliswa ngokuphuma, ukutsalwa kwe-filament, ukuluka, kunye nokwenza iingxowa. I-PP yi-thermoplastic ecacileyo, ene-semi-crystalline enamandla aphezulu, i-insulation elungileyo, ukufunxwa kwamanzi okuphantsi, ubushushu obuphezulu bokubeka ubushushu, uxinano oluphantsi, kunye ne-crystallinity ephezulu, okwenza ibe yeyona nto iphambili kwiingxowa ezilukiweyo. Ii-fillers eziguquliweyo zihlala ziquka i-glass fiber, i-mineral fillers, kunye ne-thermoplastic rubber.
Iingxowa zeplastiki ezilukiweyo zineendlela ezahlukeneyo zokusetyenziswa. Okwangoku, zisetyenziselwa ikakhulu ukupakisha imveliso yezolimo, ukupakisha iingxowa zesamente, ukupakisha ukutya, ubunjineli bejografi, uthutho lwezokhenketho, kunye nezixhobo zokulawula izikhukula.
Iingxowa ezilukiweyo zahlulwe kaninzi zibe ziintlobo ezintathu: iingxowa zeplastiki ezilukiweyo (iingxowa ezilukiweyo ezingenalaminati), iingxowa zeplastiki ezilukiweyo ezidityanisiweyo, kunye neempahla ezahlukeneyo ezilukiweyo.
Inkqubo yokuvelisa iplastikiiingxowa ezilukiweyongolu hlobo lulandelayo: ilaphu elilukiweyo liyaprintwa, lisikwe, lize lithungwe ukuze libe ziingxowa ezilukiweyo. Ngokuxhomekeke kwizixhobo ezisetyenzisiweyo, ukusika kungenziwa ngaphambi kokuprinta, okanye ukushicilela kungenziwa ngaphambi kokusikwa. Ukusika nokuthunga ngokuzenzekelayo kunokugqibezela iinkqubo zokuprinta, ukusika, kunye nokuthunga ngokuqhubekayo. Kunokuvelisa neengxowa zevalvu, iingxowa ezizaliswa ezantsi, njl. Kwilaphu elilukiweyo elilula, ukubopha phakathi komthungo kungenziwa ngaphambi kokwenza iingxowa.
Inkqubo yokuvelisa i-compositeiingxowa zeplastiki ezilukiweyoibandakanya ukugquma okanye ukugquma ilaphu elilukiweyo, izinto zokugquma, kunye nephepha okanye ifilimu. Ilaphu elityhubhu okanye ilaphu elivelayo lingasikwa, liprintwe, kwaye lithungwe ukuze kwenziwe iingxowa eziqhelekileyo ezithungiweyo ezisezantsi. Lingaphinda libethelwe, lifakwe umphetho, lisikwe, liprintwe, kwaye lithungwe ukuze kwenziwe iingxowa zesamente. Ilaphu elivelayo lingaba yi-center-seam bonding, liprintwe, lisikwe, kwaye lincamathiselwe ezantsi ukuze kwenziwe iingxowa ezincamathiselweyo ezisezantsi. Lingadityaniswa kwaye liqengqwe ukuze kwenziwe iitarpaulins kunye nee-geotextiles.
Amalaphu alukiweyo angagqunywa okanye angagqunywa ukuze kuveliswe iitarpaulins, iigeotextiles, njl. Amalaphu eTubular angakrazulwa aze agqunywe okanye angagqunywa ukuze kuveliswe iitarpaulins okanye iigeotextiles, njl.
2. Iindlela kunye neendlela zokucubungula iingxowa ezilukiweyo
2.1 Ukwahlulwahlulwa kwezakhi zofuzo
Ukuxubana kweplastiki linyathelo elibalulekileyo ekucutshungulweni kwemveliso yeplastiki. Uninzi lwezinto ezikrwada zeplastiki kufuneka zixutywe emva kokwenziwa ngaphambi kokusetyenziswa, kwaye obu buchwephesha buchaphazela ngokuthe ngqo umgangatho weemveliso zeplastiki. Inkqubo ephambili yokuxubana ibandakanya: ukuxuba, ukukhupha, ukuhluza, ukupholisa amanzi, ukutsala, ukupeyinta, ukomisa, kunye nokupakishwa.
Umgubo wePolypropylene, izongezo ezahlukeneyo, kunye ne-activated calcium carbonate zongezwa kwi-high-speed mixer ngomlinganiselo othile kunye nolandelelwano. Emva kokuxuba ngesantya esiphantsi ukuya kwesikhulu kangangexesha elithile, umxube ufakwa kwi-hopper kwaye uhanjiswe nge-screw feeder. Izinto zingena kwi-barrel ngokusebenzisa indawo yokungena, apho zinyibilikiswa kwaye zenziwe iplastiki yi-barrel kunye ne-screw, zikhutshwa rhoqo kwaye zizinzile zibe yimicu. Imicu ipholiswa kwaye ibunjwe kwitanki yamanzi, emva koko isuswe ngumngxuma yifeni ekhupha umswakama, ipholiswe ngumngxuma, kwaye emva koko ipelletizer yi-pelletizer. Emva kokuhlolwa ngesikrini esingcangcazelayo, imicu ihanjiswa yifeni ehambisa umbane ukuya ebhedini ekhupha umswakama ukuze yomiswe yibhedi ekhupha umswakama. Ekugqibeleni, imicu ingena kwitanki yezinto, kwaye i-feeder ifunxa izinto ezivela etankini ziye kwitanki yokugcina. Emva kokuba ii-pellets ziphumelele ukuhlolwa, zipakishwa ngobuninzi, zigqibezela yonke inkqubo yemveliso. 2.2 Ukuzoba i-Yarn Ukuzoba i-yarn, okwaziwa ngokuba ngumzobo we-flat yarn okanye ukusika i-fiber, yinkqubo ephambili kwimigca yokuvelisa iingxowa ezilukiweyo; Ngokufanayo, iyunithi yokuzoba intambo sisixhobo esiphambili somzi-mveliso wokwenza ingxowa elukiweyo. Umgangatho wenkqubo yokuzoba intambo uchaphazela ngokuthe ngqo umgangatho wangaphakathi nowangaphandle wemveliso.
Inkqubo yolusu oluthe tyaba ibandakanya: ukuguqulwa kwezinto eziluhlaza, ukuxuba, ukufaka umbala, ukuzalisa, ukwenziwa, imiba yokulwa nokwaluphala kunye nokulwa nokubola, ubushushu, uxinzelelo, kunye nolawulo lwesantya sokuhamba ngexesha lokukhupha, ukuziphatha kwe-rheological ngexesha lokukhupha, imiba yokusetyenziswa kwamandla kunye nemveliso, umlinganiselo wokutsala, umlinganiselo wokuqhushumba, umlinganiselo wokutsala, ukupholisa ikristale, ukuqhelaniswa, unyango lobushushu kunye nemiba yokubumba, ukwakheka ngexesha lokusonga, kunye nokuhlolwa komgangatho wee-spindles zelusu.
Emva kokuba izinto eziluhlaza zingene kwi-extruder, zifakwa kubushushu bangaphandle kwi-190-250℃ kwaye zichetywe phakathi kwesikrufu kunye nebharele. Emva kokuba phantse zenziwe iplastiki ngokupheleleyo, izinto zikhutshwa ngobuninzi kwaye ziphantsi koxinzelelo oluqhubekayo. Emva kokuba zenziwe entloko yedayi, ziba yifilimu enyibilikisiweyo engena emanzini abandayo. Emva kokuba ipholile, ifilimu iyanqunyulwa ibe yi-filaments ngeeblades. Ii-filaments zolulwa kubushushu obuphezulu kwi-oven yobushushu obuphezulu de zenze iintambo ezisicaba. Intambo esicaba emva koko ifakwa kubushushu kwii-hot rollers, inciphe ngesantya esiphantsi sokutsala, kwaye icutshungulwa kubushushu obuphantsi zii-cold rollers. Ekugqibeleni, ifakwa kwimo yinkqubo yokujika ye-differential tension.
Iinkqubo zokuvelisa intambo ethe tyaba zingahlulwa ngokwendlela yokwenziwa kwefilimu (ifilimu yetyhubhu, ifilimu ethe tyaba); ngendlela yokupholisa emva kwefilimu (ukupholisa umoya, ukupholisa amanzi, kunye nokupholisa okungapheliyo); ngendlela yokudweba kunye nokufudumeza (ipleyiti eshushu, iirola ezishushu, umoya oshushu); nangendlela yokujikeleza i-spindle (i-centralized cycloidal winding, i-single-spindle torque motor winding, kunye ne-magnetic torque winding).
