Njengoba izidingo zokuvikelwa kwemvelo emhlabeni wonke ziqhubeka, izikhwama zokupakisha zepulasitiki zephepha ziya kancane kancane endleleni efanele, pho-ke yiziphi izinzuzo zezikhwama zokupakisha zepulasitiki zephepha? Isikhwama sokupakisha sepulasitiki sephepha siwuhlobo lwesikhwama sokupakisha esisha esinamandla aphezulu, esilwa nokuguga, esimelana nokushisa okuphezulu, esingangeni umswakama, esiphefumulayo, esingenabuthi futhi esingenangozi. Sisetshenziswa kabanzi ekudleni okupakishiwe, ukudla okuqandisiwe okusha, isitashi, i-casein, ukudla, izinto zokwakha, amakhemikhali, amaminerali kanye neminye imboni yesikhwama sezimpahla.
Inezinzuzo eziyisithupha ezilandelayo
A, engangenisi umswakama
Ngenxa yokuthi i-PVA inokuguquguquka okuhle kakhulu kanye nokwakheka kwefilimu, enkambisweni yokucindezela i-compound izokwakha ungqimba lwefilimu engxenyeni engaphakathi yesikhwama sokupakisha sephepha-plastiki, idlale indima yokunamathela okuhlanganisiwe kanye nokumelana nomswakama. Enye indawo inezimbobo eziningi ezingabonakali, ezingavimbela ngempumelelo ama-molecule amanzi angaphandle kwesikhwama sepulasitiki sephepha ukuthi angangeni esikhwameni.
Okwesibili, ukumelana nokushisa okuphezulu
Amandla esikhwama sephepha-plastiki alawulwa kakhulu yi-warp kanye ne-weft. Intambo ye-pYLON encibilikayo emanzini inezici zamandla okuphuka njalo ku-180 ℃. Indawo yokushisa yephepha ingu-183 degrees, ngakho-ke isikhwama esihlanganisiwe sinezici zokumelana nokushisa okuphezulu.
Okwesithathu, ukulwa nokuguga
Ngenxa yokuthi iphepha alilula ukuguga izinto zesitshalo, linezici ze-opaque, isikhwama sepulasitiki sephepha ngaphakathi nangaphandle kwephepha ngaphansi kwemisebe ye-ultraviolet singavikela ngempumelelo iphepha ukuthi lingagugi, ukuze isikhwama kanye nezici ze-anti-aging.
Okwesine, ukuqina okuphezulu
Amandla esikhwama sepulasitiki sephepha alawulwa kakhulu yisiqondiso se-warp kanye ne-weft. Ngenxa yokujikeleza kwethreyi ye-weft okuphikisana newashi, ubuso bangaphandle bephepha langaphakathi buzokwakha izakhiwo eziningi ze-mesh ezingonxantathu, okwandisa kakhulu ukucindezeleka kwangaphakathi kwesikhwama sokupakisha, ukuze isikhwama sokupakisha sibe namandla aphezulu.
Ezinhlanu, izikhwama ezinqwabelanayo ezingasheleli
Ngoba enkambisweni yenhlanganisela yokucindezela, ubuso bangaphandle besikhwama sepulasitiki sephepha bakha isakhiwo esiningi se-triangular mesh, kwandisa i-friction coefficient yobuso bangaphandle besikhwama, ukuze isikhwama singasheleli enkambisweni yokufakwa (kufika kuma-degree angu-40). Ibhokisi Lepulasitiki - ipulatifomu yokuhlanganisa uchungechunge lwemvelo "lwe-inthanethi + ipulasitiki" embonini yokupakisha ipulasitiki yokudla
Vikela imvelo
Njengoba intambo encibilika emanzini ye-pVA ingaphathwa nge-resin acetal, ingancibilikiswa emanzini ashisayo angu-80 ukuze yakhe iglue. Ngemva kokucwiliswa, izendlalelo zangaphakathi nezangaphandle zephepha zingaphinde zisetshenziswe ukuze kwenziwe iphepha eliphinde lisetshenziswe ngaphandle kokungcolisa indawo ezungezile.
Isikhwama sephepha-plastiki, esaziwa nangokuthi isikhwama sephepha esihlanganisiwe esinezintathu, siyisitsha esincane esikhulu, ikakhulukazi ngezisebenzi noma nge-forklift. Kulula ukuthutha inani elincane lempuphu enkulu nezinto ezihlanganisiwe. Sinezici zamandla aphezulu, ukungangenwa kwamanzi okuhle, ukubukeka okuphezulu, ukulayisha nokukhulula okulula, sithandwa futhi sisetshenziswa kakhulu ekupakisheni.
Izikhwama zepulasitiki zephepha zisetshenziselwa kakhulu ukupakisha izinto zokwakha, izikhwama ze-mortar, i-putty powder, ukudla, izinto zokusetshenziswa zamakhemikhali kanye nezinye izinto eziqinile ze-powdery noma ze-granular kanye nezinto eziguquguqukayo. Eminyakeni yamuva nje, zisetshenziswe kabanzi ekupakisheni okusheshayo ekuthengisweni kwe-inthanethi, izitika zodonga ezinezilinganiso ezintathu, izihlalo zezimoto, izembozo zezihlalo kanye neminye imikhakha.
