i-ppgi eyenziwe ngopende ngaphambili yekhoyili yensimbi eluhlaza
Ikhoyili yensimbi enombala ependwe kusengaphambili i-ppgi iwuhlobo lwepuleti lensimbi elinamekwe ngombala.Kungumkhiqizo owenziwe ngokufaka upende ngendlela ye-roller coating, bese ubhaka nokupholisa ngemva kokwelashwa kokuguqulwa.Inqubo yokukhiqiza iguqukile isuka ekujikeni okukodwa kanye nokomisa okukodwa kuya kokunamathiselwe okubili nokomisa okubili.Kukhona futhi inqubo yokugcoba kathathu kanye nenqubo yokubhaka kathathu.Miningi imibala yamabhodi anamapulangwe anemibala, efana nompunga omhlophe, oluhlaza okwesibhakabhaka, osawolintshi, oluhlaza okwesibhakabhaka, obomvu okwegazi, obomvu ngezitini, omhlophe wezinyo lendlovu, oluhlaza okotshani, njll. Isimo esingaphezulu samashidi anombala we-ppgi singahlukaniswa sibe sinandisiwe evamile. amabhodi, amabhodi aqoshiwe namabhodi aphrintiwe.Ukusetshenziswa kwemakethe kwamakhoyili ensimbi e-PPGI ahlukaniswe ikakhulukazi ngokwakha, izinto zikagesi zasendlini nezokuthutha.
Ikhoyili yensimbi eyenziwe ngopende eyenziwe ngaphambili ye-Ppgi isetshenziswa kakhulu futhi inezici zokungangcoli, ukumelana nesimo sezulu, ukumelana nokugqwala, kanye nokusetshenzwa okuphezulu.Ikhoyili yensimbi ependwe ngaphambili ye-Ppgi isetshenziswa kakhulu ezimbonini ezihlukahlukene ezifana nezokwakha, izinto zikagesi zasendlini, ukupakisha, imishini, nokunye.Ibandakanyeka ezicini ezahlukene ezifana nokucubungula, ezokuthutha, ukuhlobisa kwangaphakathi, ezokwelashwa kanye nezimoto.
Izinga lokusebenzisa ikhoyili yensimbi ye-ppgi ezintweni zasendlini ngu-31%, futhi ukusetshenziswa kwayo ekwakhiweni kubalelwa ku-63%.Kubaluleke kakhulu embonini yezokwakha.Isetshenziswa kancane kwezinye izici, cishe u-6%.Amashidi ensimbi anama-galvanized asetshenziswa njengama-substrates e-coatings ahlinzeka ngokuvikela nemisebenzi yokuhlukanisa.Lokhu kuvimbela ukugqwala futhi kwandise impilo yesevisi yepuleti lensimbi ngo-50%, kuyilapho futhi kunikeza isivikelo esinamandla.
Ezifundeni ezahlukene kanye nezingxenye zokusetshenziswa, ngisho noma inani elifanayo le-galvanizing, upende kanye ne-ppgi steel sheet eluhlaza kusetshenziswa ubukhulu obufanayo bokugqoka, impilo yabo yesevisi ihluke kakhulu.Ezindaweni zezimboni nesogwini, ukuchayeka ku-sulphur dioxide noma usawoti emoyeni kusheshisa ukugqwala futhi kunciphisa impilo yesevisi.Ngesikhathi sezimvula, ukugqwala kuzobola ngokushesha ngemva kokumanziswa yimvula isikhathi eside, ngaleyo ndlela kunciphise ukuphila kwayo kokusebenza.
Izakhiwo nezimboni ezenziwe ngamashidi okufulela anombala oluhlaza zinganweba impilo yazo yesevisi uma ngokuvamile zikhukhulwa yimvula.Uma izinyathelo zokuphepha ezidingekayo zingathathwa, zizoba sengozini enkulu yesulphur dioxide, usawoti kanye nothuli.Ngakho-ke, lapho uklama, umthambeko wophahla kufanele ukhuliswe.Uma sikhulu, uthuli oluncane nokunye kunqwabelana futhi impilo yayo yesevisi iba yinde.Izingxenye nezindawo ezingavami ukugezwa yimvula kufanele zihlanzwe njalo.
