Iimpawu zokuSebenza kunye noHlalutyo lweSicelo sePVC Tarpaulin
Iseyile yePVC, into eqhelekileyo eyenziweyo, isetyenziswa kakhulu kushishino, kwezolimo, kulwakhiwo, nakwizicelo zangaphandle ngenxa yeempawu zayo ezibalaseleyo zomzimba kunye neekhemikhali. Icandelo layo eliphambili yi-polyvinyl chloride (i-PVC), eyenziwa kunye nezongezo ezifana ne-plasticizers kunye ne-stabilizers, okukhokelela kwiintlobo ezahlukeneyo zeenzuzo zokusebenza ezizodwa.
Okokuqala, i-tarpaulin ye-PVC inikezela ngeempawu ezintle zokungangeni manzi. Ubume bayo bemolekyuli obubambeneyo kunye nomphezulu ogudileyo kuthintela ngokufanelekileyo ukungena kokufuma, kusenze ukuba siqhele ukusetyenziselwa iawnings, iintente, kunye nezigqubuthelo zeyadi yempahla. Nangona ukutshatyalaliswa kwexesha elide kwimvula, igcina iimpawu zayo zokukhusela amanzi, ikhusela izinto ngaphakathi.
Okwesibini, i-tarpaulin ye-PVC iyaxhathisa kwimozulu{0}}. Ixhathisa imitha ye-UV, amaqondo obushushu aphezulu kunye naphantsi, kwaye ayinakuchaphazeleka ekugugeni okanye ukuba brittleness. Iseyile yePVC enyangwa ngokukodwa igcina ukuthamba kunye nokomelela kwayo nasemva kokuba{3}}ixesha elide isetyenziswa ngaphandle, yandisa ubomi bayo benkonzo. Ngaphaya koko, ukumelana kwayo komoya okugqwesileyo kuyenza ilungele izicelo ezifana nezakhiwo zethutyana kunye nokubiyelwa kwendawo yokwakha.
Iseyile yePVC ikwabonelela ngokugruzuka okugqwesileyo kunye nokumelana nokukrazula. Xa kuthelekiswa neseyile yemveli okanye ezinye izinto, iiseyile zePVC zomelele kwaye zinokumelana nokungqubana okuthile koomatshini kunye neempembelelo zangaphandle. Zizilungele izicelo ezibandakanya ukuhamba rhoqo okanye imithwalo enzima, njengokugcinwa kwempahla kunye nolungiselelo.
Ngokumalunga nokumelana nomlilo, ezinye iiseyile ze-PVC ziphathwa ngonyango lwe-flame retardant, olubonelela ngeqondo elithile lokumelana nomlilo, ukunciphisa ukusasazeka komlilo kunye nokuphucula ukhuseleko. Iiseyile zePVC zikwalula ukuzicoca kunye nokuzigcina, kwaye amabala angaphezulu anokususwa ngokusula, awenze alungele ukusetyenziswa ixesha elide{1}}.
Nangona kunjalo, iiseyile zePVC zinemida ethile, njengokuphefumla kakubi, zizenza zingafaneleki kwindawo efuna umoya. Ngaphaya koko, ezinye{1}}ezikumgangatho ophantsi wePVC iitarpaulis zinokuqulatha iiplastiki ezinobungozi ezinokukhupha izinto ezinobungozi kwindawo-zobushushu obuphezulu. Ngoko ke, kubalulekile ukukhetha iimveliso ezihlangabezana nemigangatho yokusingqongileyo.
Ngamafutshane, iiseyile zePVC, ngenxa yeepropathi zazo ezigqwesileyo ezifana nokungangeni kwamanzi, ukumelana nemozulu, kunye nokumelana nokunxiba, lukhetho olufanelekileyo kumashishini amaninzi. Ukukhetha okufanelekileyo kunye nokugcinwa okufanelekileyo kunokwandisa inzuzo yabo kunye nokuhlangabezana neemfuno zeemeko ezahlukeneyo.
