I-DIN 30670 ibhekisela kwiingubo ze-polyethylene kwimibhobho yentsimbi kunye nezixhobo-Iimfuno kunye novavanyo.

Lo mgangatho uchaza iimfuno zemveliso-esetyenzisiweyo kwi-polyethylene-based based coatings, kunye ne-multi-layered sintered polyethylene-based based coatings ukwenzela ukukhusela ukuhlwa kwemibhobho yentsimbi kunye nokufakelwa.Iingubo zilungele ukukhuselwa kwimibhobho yentsimbi engcwatywe okanye ephantsi kwamanzi kumaqondo obushushu boyilo-40 °C ukuya kuthi ga +80°C. Umgangatho wangoku uxela iimfuno zokwaleka ezisetyenziswa kuzoLSAW umbhobho wentsimbi or imibhobho yentsimbi engenamthungo kwayeizixhobo esetyenziselwa ukwakhiwa kwemibhobho yokuhambisa ulwelo okanye iigesi.Ukusebenzisa lo mgangatho kuqinisekisa ukuba i-PE yokugubungela inika ukhuseleko olwaneleyo kumatshini, imithwalo ye-thermal kunye neekhemikhali ezenzeka ngexesha lokusebenza, ukuthutha, ukugcinwa kunye nokufakwa.I-DIN ISO 21809-1 ixela iimfuno kumgangatho wamazwe ngamazwe zomaleko-ntathu wepolyethylene- kunye ne-polypropylene esekwe kwimibhobho yentsimbi ye-petroleum kunye neenkqubo zothutho zegesi yendalo.Le mimandla ilandelayo yesicelo ayigqunywanga yi-DIN EN ISO 21809-1:─zonke iileyile ezisekwe kwi-polyethylene kwimibhobho yentsimbi kunye nezixhobo ezisetyenziselwa ukuhambisa kunye nokuhanjiswa kwamanzi kunye namanzi amdaka;─zonke iingubo ezisekelwe kwi-polyethylene kwimibhobho yentsimbi kunye nofakelo kwimibhobho yokuhambisa i-gaseous kunye ne-liquid media;─I-single- kunye ne-multi-layer sintered polyethylene-based based coatings kwimibhobho yentsimbi kunye nezifakelo ezisetyenziselwa imibhobho yokuthutha kunye nemibhobho yokuhambisa Umgangatho okhoyo uhlala usemthethweni kule mihlaba ingentla yesicelo.Iingubo ezine-polyethylene ezisekelwe kwimigangatho emibini zisemgangathweni kwinqanaba laseYurophu kwi-DIN EN 10288 eyapapashwa ngoDisemba 2003.

Izinto eziphathekayo ziya kukhethwa ngokwengqiqo ye-coater kuba, kuxhomekeke kwindlela yokufakela kunye neyokugquma, izinto ezahlukeneyo zingasetyenziselwa ukuthobela iimfuno ezincinci ezichazwe kulo mgangatho wokugqitywa kokugqitywa.Naziphi na iimfuno ezitenxayo zomthengi malunga nezixhobo eziza kusetyenziswa ziya kuxhomekeka kwimvumelwano. Umphezulu uya kulungiswa ngokususa irusi ngendlela yokucoca uqhushumbo.Ukucoca ukuqhuma kunye naluphi na umsebenzi ofunekayo olandelayo awuyi kubangela ukunciphisa ubuncinci bodonga oluchazwe kwimigangatho yokunikezelwa kwezobugcisa kumbhobho wensimbi.Uthuli olushiyekileyo luya kususwa ngaphambi kokugquma.
