Ipulasitikiizikhwama ezilukiwezenziwe nge-polypropylene (PP) njengezinto zokusetshenziswa eziyinhloko, futhi zenziwa ngokukhipha, ukudweba ngocingo, ukuluka, ukunitha kanye nokwenza izikhwama.
I-Polypropylene iyi-thermoplastic eguquguqukayo kanye ne-semi-crystalline thermoplastic enamandla amakhulu, ukwahlukanisa okuhle, ukumuncwa kwamanzi aphansi, izinga lokushisa eliphezulu le-thermoforming, ukuminyana okuphansi kanye nokucwebezela okuphezulu.Yimpahla eyinhloko yezikhwama ezilukiweyo.Izihlungi eziguquliwe ngokuvamile zihlanganisa imicu yengilazi, izigcwalisi zamaminerali, irabha ye-thermoplastic, nokunye okunjalo.
Izikhwama zepulasitiki ezilukiwe zinezinhlobonhlobo zezicelo.Njengamanje, izikhwama zepulasitiki ezilukiwe zisetshenziselwa kakhulu ukupakishwa kwemikhiqizo yezolimo, ukupakisha izikhwama zikasimende, ukupakisha ukudla, ubunjiniyela be-geotechnical, ezokuthutha ezokuvakasha, izinto zokulawula izikhukhula, njll. Izikhwama ezilukiweyo ikakhulukazi zifaka izikhwama ezilukiweyo zepulasitiki (izikhwama ezilukiwe ngaphandle kwefilimu), ipulasitiki elukiwe eliyinhlanganisela. izikhwama nezindwangu ezehlukene ezilukiwe.Inqubo yokukhiqiza izikhwama zepulasitiki ezilukiwe imi kanje: ukuphrinta kwe-weave, ukusika, nokuthunga ezikhwameni ezilukiweyo.
Kuye ngemishini esetshenziswayo, ingasikwa kuqala bese inyatheliswa, noma inyatheliswe bese isikwa.Abathungi abazenzakalelayo bangakwazi ngokuqhubekayo ukuqedela ukuphrinta, ukusika, ukuthunga nezinye izinqubo, futhi bangenziwa futhi babe amaphakethe ama-valve, amaphakethe aphansi, njll. Ezindwangu ezilukiwe ezingenalutho, izikhwama zingenziwa ngokunamathisela umthungo ophakathi nendawo.Inqubo yokukhiqiza yezikhwama zepulasitiki ezilukiweyo iwukuhlanganisa noma ukugqoka izindwangu ezilukiwe, izinto zokumboza kanye nephepha noma ifilimu.Ishubhu noma ucezu lwendwangu lungasikwa, luphrintwe, luthungwe futhi lwenziwe isikhwama somthungo ovamile ongaphansi, noma lubhotshwe, lugoqwe, lunqunywe, luphrintwe futhi luthungelwe esikhwameni sikasimende, kanti indwangu etholakalayo ingaba Ukuthunga, ukunamathisela, ukuphrinta, ukusika kanye nokunamathisela emaphaketheni angaphansi.Ingakwazi futhi ukushiselwa futhi igoqwe ukwenza iseyili nama-geotextiles.Indwangu engenalutho ingagcotshwa noma ingagqokisiwe ukuze ikhiqize oseyili, ama-geotextiles, njll. , futhi izindwangu eziyi-cylindrical nazo zingagcotshwa noma zingagcotshwa ukuze kukhiqizwe iseyili noma ama-geotextiles, njll.
Izinkomba zobuchwepheshe zenqubo yokukhiqiza ucingo oluyisicaba zihlukaniswe ikakhulukazi izigaba ezine:
1. Inkomba yokusebenza komshini.Ikakhulukazi ihlanganisa amandla aqinile, amandla aqinile ahlobene, ukuphakama ngesikhathi sekhefu, isivinini somugqa, ukuchezuka komugqa wokuminyana;
2. Inkomba yokuguqulwa komzimba namakhemikhali.Kukhona ikakhulukazi ukuguqulwa okuxutshiwe, isilinganiso sokuxuba, isilinganiso sokusebenza sokungeza okungeziwe, kanye nesilinganiso sokuhlanganisa semfucuza nezinto ezigaywe kabusha;
3. Ukubekezelelana dimension index.Kukhona ikakhulukazi ukujiya kocingo oluyisicaba, ububanzi bezintambo eziyisicaba nokunye.
4. Inkomba ye-rheological yomzimba.Kukhona ikakhulukazi isilinganiso sokusalungiswa, isilinganiso sokunwetshwa, isilinganiso sokusalungiswa kanye nesilinganiso sokuhlehla;
Izinto ze-polyethylene enkambweni yokugqoka isikhwama ziyashiswa, ziyancibilika, zenziwe ngepulasitiki futhi zikhishwe ngokuqina yi-extruder;
Cindezela kufilimu eyi-cylindrical ngekhanda lokufa;ukwethula igesi ecindezelwe ukuze ikhule ukuze yenze amabhamuza ashubhu;
Sebenzisa indandatho yomoya opholile ukuze uphole futhi ulolonge, donsa i-herringbone bese uyigoqa;
Ngokusebenzisa ama-traction roller, ama-roller okushayela kanye nama-winding rollers,
Okokugcina, inqubo yokusika nokushisa isetshenziselwa ukuqedela ukukhiqizwa kwesikhwama sangaphakathi se-lining, futhi ekugcineni isikhwama sigcwele.
I-polypropylene ehlanzekile yokukhiqizwa kwentambo eyisicaba ayikwazi ukuhlangabezana nezidingo, futhi ingxenye ethile ye-polyethylene ephezulu yokucindezela, i-calcium carbonate kanye ne-masterbatch yombala kufanele yengezwe.Ukwengeza inani elincane le-polyethylene enengcindezi ephezulu kunganciphisa i-viscosity kanye nesivinini sokuncibilika kokugeleza kwezinto ngesikhathi sokukhipha, kukhuphule uketshezi, kuthuthukise ukuqina nokuthambile kwentambo eyisicaba nesikhwama esilukiwe, kugcine ukunwebeka okuthile ngesikhathi sekhefu, futhi kuthuthukise okuphansi. umthelela wokushisa we-polypropylene..
Ukwengezwa kwe-polypropylene ehlanganisiwe kunganciphisa izinga lokushisa lokucubungula nokucindezela.Ithuthukisa ukugeleza kwezinto ezibonakalayo nokunamathela, futhi ikhulise amandla okudonsa.Ukwengezwa kwe-calcium carbonate kungashintsha amaphutha okukhanya nokungafihli, kunciphise ugesi omile oyingozi okhiqizwa ukungqubuzana phakathi nokwelula nokweluka, kwandise ukunamathela kukayinki wamaphethini ophawu lokuhweba oluphrintiwe, futhi kunciphise ukushwabana kwemvelo kwemikhiqizo eqediwe ngesikhathi sokulondoloza.
