Kwishishini lokugquma, i-primer etyebileyo kwi-epoxy zinc kunye ne-primer etyheli ye-epoxy zinc zizinto ezimbini ezisetyenziswa kakhulu kwi-primer.
Nangona zombini zine-zinc, kukho umahluko omkhulu ekusebenzeni nasekusetyenzisweni kwazo. Eli nqaku liza kuthelekisa iinkalo ezahlukeneyo ze-epoxy zinc-rich primer kunye ne-epoxy zinc yellow primer ukuze ziqonde ngcono umahluko wazo.
Iimpawu zokungagqwali: Iiprimer ezityebileyo ze-epoxy zinc zaziwa ngomxholo wazo ophezulu we-zinc kwaye ngenxa yoko zineempawu ezintle zokungagqwali. Iprimer etyebileyo ye-zinc iyamelana ngempumelelo nokugqwala kunye ne-oxidation, yandisa ubomi bokugquma. Umxholo we-zinc kwiprimer etyheli ye-epoxy zinc uphantsi kakhulu, kwaye ukusebenza kwayo kokungagqwali kubuthathaka kakhulu.
Umbala kunye nenkangeleko: I-primer etyebileyo ye-epoxy zinc inombala ongwevu okanye ongwevu ngesilivere. Inomphezulu ofanayo nogudileyo emva kokupeyintwa kwaye ifanelekile njenge-baUmbala we-epoxy zinc yellow primer utyheli kwaye usetyenziswa kakhulu ukubonisa inani leeleya zokugquma ngexesha lokwakhiwa.
Amandla okubopha: I-primer etyebileyo ye-epoxy zinc ineempawu ezilungileyo zokubopha kwi-substrate yokugquma kwaye inokunamathela ngokuqinileyo kumphezulu ongaphantsi. Xa kuthelekiswa, ii-primer ezityheli ze-epoxy zinc zinamandla okubopha aphantsi kancinci kwaye zinokufuna ukuqina okongeziweyo ukuphucula ukunamathela kwengubo.
Iindawo zokusetyenziswa: Ngenxa yokuba i-primer etyebileyo kwi-epoxy zinc ineempawu eziphezulu zokulwa nokugqwala, idla ngokusetyenziselwa ukugquma izakhiwo ezinkulu ezifana nezakhiwo zentsimbi, iinqanawa, kunye neebhulorho. Iindawo eziphambili zokusetyenziswa kwe-primer etyheli ye-epoxy zinc kukupeyinta okuneenkcukacha kweemoto, izixhobo zoomatshini kunye nefenitshala.
Ukushwankathela, kukho umahluko othile phakathi kweprimer etyebileyo ye-epoxy zinc kunye neprimer etyheli ye-epoxy zinc ekusebenzeni okuchasene nokugqwala, umbala kunye nenkangeleko, amandla okubopha kunye neendawo zokusetyenziswa. Xa ukhetha izixhobo zeprimer, kufuneka kwenziwe ukhetho olufanelekileyo ngokusekelwe kwiimfuno ezithile kunye neempawu zento yokupeyinta ukuqinisekisa umgangatho kunye nobomi benkonzo yokwaleka.
