Izici Zobuchwepheshe Nokuhlaziywa Kwesicelo Sezakhiwo ze-PVC Tarpaulin

Iseyili ye-PVC iyinto esebenzayo esetshenziswa kabanzi ezakhiweni zesikhashana, imbobo yezindlu zokugcina impahla, ukukhangisa kwangaphandle, neminye imikhakha. Isakhiwo sawo sithinta ngokuqondile ukuqina komkhiqizo, ukungangeni kwamanzi, nokuvumelana nezimo zemvelo. Lesi sihloko sichaza ngokuhlelekile izici zesakhiwo kanye nezinzuzo zobuchwepheshe ze-PVC tarpaulin kusukela kumbono wokwakheka kwezinto, isakhiwo se-interlayer, izakhiwo zokusebenza, nezimo zohlelo lokusebenza ezijwayelekile.

 

1. Ukwakhiwa Kwezinto Eziyisisekelo ze-PVC Tarpaulin

Isisekelo sesisekelo se-PVC (i-polyvinyl chloride) seseyili yi-polyvinyl chloride resin, eyakhiwe ibe into ehlanganisiwe ye-polymer ngokungeza izithasiselo ezifana nama-plasticizers, ama-stabilizer, neziqinisi ze-UV. Ama-Plasticizers (afana nama-phthalates) athuthukisa ukuguquguquka kwezinto, okuyivumela ukuthi igcine i-ductility ngisho emazingeni okushisa aphansi. Iziqinisi ezifana ne-calcium zinc noma i-organotin zithuthukisa ukumelana nokushisa nokumelana nokuguga, zandise impilo yesevisi kaseyili. Eminye imikhiqizo{3}ephezulu ephezulu iphinde ihlanganise ama-flame retardant noma izithako ezilwa namagciwane ukuze ihlangabezane nezimfuneko ezithile zohlelo lokusebenza.

 

II. Izimiso-eziningi Zokwakhiwa Kwesakhiwo Esihlanganisiwe Sezendlalelo

Oseyili besimanje be-PVC ngokuvamile basebenzisa-ungqimba oluningi-lokukhipha noma inqubo eyinhlanganisela yokuhlanganisa ukuze bakhe izendlalelo zokusebenza ezihlukene:

Isendlalelo sesisekelo (isendlalelo esisekelayo): Senziwe-nge-polyester fiber ephezulu (efana ne-PET) noma i-glass fiber mesh, sinikeza useyili wawo wonke amandla okunyakazisa kanye nokuzinza kwe-dimensional, ukuvimbela ukuwohloka okubangelwa amandla angaphandle.

Isendlalelo esisebenzayo esimaphakathi: Ikakhulukazi yakhiwe ifilimu ye-PVC, iboshelwa kusisekelo ngokusebenzisa-i-melt bonding eshisayo noma ngekhalenda. Lesi sendlalelo sinquma ukusebenza okuyinhloko kweseyili. Isibonelo, ukulungisa ukuminyana kwe-PVC kungafinyelela isilinganiso esingangeni manzi (isb, ukufinyelela ku-IPX7), kuyilapho ukungeza izinhlayiya ze-carbon black kuthuthukisa kakhulu ukumelana ne-UV (amanani e-UPF ​​edlula 50+).

Isendlalelo sokwelapha esingaphezulu: Eminye imikhiqizo igcotshwe nge-polyurethane (PU) noma ivarnish ye-acrylic ukuze yenze{0}}ifilimu evikelayo engaguquki futhi engabizi, kuyilapho ithuthukisa ukushelela kwendawo ukuze kuncishiswe ukunqwabelana kothuli namanzi emvula.

 

III. Ukuqaliswa Kwesakhiwo Sezimo Ezisemqoka Zokusebenza

Idizayini yesakhiwo yamaseyili e-PVC ithinta ngqo ukusebenza kwawo kwangempela:

Ukungangeni kwamanzi: I-PVC eqhubekayo, eminyene (imvamisa engu-0.1-0.5mm ubukhulu) inikeza ukumelana kwamanzi okuphelele. Ama-Seams aqiniswa{3}}ngemvamisa yokushisela noma nge-sealing tape ukuqinisekisa ukuvuza{4}ukusebenza kobufakazi ngisho nangaphansi kokuchayeka isikhathi eside emvuleni naseqhweni.

Ukumelana Nesimo Sezulu: Ukusabalalisa okufanayo kwezimuphi ze-UV ngaphezulu, kuhlanganiswe nomthelela we-synergistic wesendlalelo esilwa{0}}nokuguga, kuqinisekisa ukusebenza okuzinzile emazingeni okushisa asuka ku- -30℃kuya ku-70℃, nempilo yangaphandle yesevisi yeminyaka engu-5-10.

Amandla Emishini: Amandla e-warp kanye ne-weft tensile ngokuvamile adlula u-200N/5cm (ngokuvumelana namazinga e-DIN), futhi amandla okudabula adlula u-150N, ayenza imelane nemithwalo eguquguqukayo efana nemimoya enamandla nokunqwabelana kweqhwa.

 

IV. Izimo Zokusebenza Ezijwayelekile kanye Nokuhambisana Kwesakhiwo

Izimo zohlelo lokusebenza ezihlukene zibeka izidingo ezihlukene ezakhiweni zikaseyili ze-PVC:

Izakhiwo zesikhashana (njengamatende okusiza ezinhlekeleleni): Ezigcizelela ukumiswa okungasindi nokusheshayo, zisebenzisa ungqimba olukabili-, isakhiwo esingangeni moya esinamafreyimu e-aluminium alloy kanye nolayini lwangaphakathi ukuze kuthuthukiswe ukushisa okushisayo.

Isembozo se-Warehouse: Igcizelela umthwalo-ukumelana nokubhoboza, isendlalelo sesisekelo sishunyekwa ngensimbi yensimbi noma i-Kevlar fiber ukuvimbela ukubhoboza ezintweni ezicijile.

Isibonisi Sokukhangisa: Ilwela ukudluliswa kokukhanya okuphezulu nokugcwala kombala, isendlalelo sokuphrinta esingaphezulu siboshelwa ku-substrate ye-PVC ngobuchwepheshe bokwelapha be-UV ukuze kuqinisekiswe ihluzo ezihlala isikhathi eside nezicacile.

 

Isiphetho

Ukwakhiwa okusha kweseyili ye-PVC kuyaqhubeka nokushayela ukusetshenziswa kwayo ezindaweni eziningi. Ngokuzayo, ngokwethulwa kwezithasiselo ezinobungani bemvelo (njengamapulasitiki{1}asekelwe ku-bio) nezinto ezihlakaniphile (ezifana nezinga lokushisa-njengombala ozwelayo{3}}okushintsha ama-coatings), useyili we-PVC kulindeleke ukuthi uzuze impumelelo eyengeziwe ekusebenzeni nasekusimameni, ukuhlinzeka ngezixazululo ezisebenza kahle kakhulu zobunjiniyela besimanje nezidingo zomphakathi.
