Ka wehewehe ʻana o ka mea wehe pena a me ke kumu hoʻopale pena

ʻO ka mea pena pena, ʻike ʻia hoʻi ʻo ka mea wehe pena, ka mea holoi pena a i ʻole ka mea wehe pena, he hui ia o nā hydrocarbons chlorinated, ketones, esters, alcohols, benzenes a me nā mea hoʻoheheʻe ʻē aʻe mai ka wai. ʻO ka solvent ka waiwai o ka permeating a me ka pehu ʻana i ka mea uhi, hiki ke hoʻopau pono i nā ʻano mea āpau o ka substrate i uhi ʻia (pena, uhi, etc.). Hiki ke wehe pololei ʻia ka pena a i ʻole hiki ke wehe maʻalahi ke kiʻi pena. Loaʻa ka hopena hoʻoneʻe pena o ka mea huki pena ma o ke ʻano o nā kaʻina hana kino a me ke kemika e like me ka hoʻoheheʻe ʻana, ke komo ʻana, ka pehu, ka wehe ʻana a me ka pane ʻana.

Nā ʻano o ka mea pena

Ma ka lima hoʻokahi, alkali saponifies i kekahi mau pūʻulu i loko o ka pena a hoʻoheheʻe i ka wai, ma ka ʻaoʻao ʻē aʻe, hoʻomoʻa ka mahu wela i ke kiʻi pena, e nalowale ana kona ikaika a hoʻemi i kona pili ʻana i ka metala, hui pū me ka infiltration o ka surfactant, ke komo ʻana. a me ka pili, e mae ka uhi kahiko.

ʻO ka mea pena ʻākaʻikaʻi: ʻO ka mea pena kiʻi kiʻi ʻakika ma muli o ka waika hydrochloric concentrated, hoʻololi maʻalahi ka waikawa nitric e hana i ka noe ʻakika, a loaʻa kahi hopena corrosive ma ka substrate metala, maloʻo ka phosphoric acid no ka manawa lōʻihi, loaʻa pū kekahi hopena corrosive ma ka substrate. ʻO ka sulfuric acid a me ka aluminika, ka hao a me nā metala ʻē aʻe ka hopena passivation, no laila he liʻiliʻi loa ka corrosion metala, a i ka manawa like he ikaika dehydration, carbonization a me ka sulfonation o nā mea kūlohelohe a hoʻoheheʻe ʻia i ka wai, no laila hoʻohana pinepine ʻia ka sulfuric acid. i loko o ka mea pena ʻakika.

Ka mea hoʻoheheʻe peʻa maʻamau: ʻO ka mea hoʻoheheʻe maʻamau ka peʻa pena i haku ʻia me ka mea hoʻoheheʻe kūlohelohe maʻamau i hui pū ʻia me ka paraffin wax, a me nā mea ʻē aʻe. ʻO ka mea huki pena he ikaika dehydration, carbonization a me ka hopena sulfonation ma nā mea ola. Eia nō naʻe, ʻo ka mea hoʻoheheʻe kūlohelohe i kēia ʻano o ka pena pena pena he mea maʻalahi, ʻā a me nā mea ʻawaʻawa, no laila pono e hoʻopili ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia.

ʻO ka mea hoʻoheheʻe peʻa chlorinated hydrocarbon: Hoʻopau ka mea hoʻoneʻe peʻa chlorinated hydrocarbon i ka pilikia o ka wehe ʻana i ka pena no nā uhi epoxy a me ka polyurethane, he maʻalahi ke hoʻohana, ʻoi aku ka maikaʻi a emi ʻole ka corrosive i nā metala.

ʻO ka mea pena kiʻi wai-wai: I hoʻohālikelike ʻia me ka mea hoʻoneʻe pena dichloromethane maʻamau, ʻoi aku ka ʻawaʻawa a ua like ka wikiwiki o ka wehe ʻana i ka pena. Hiki iā ia ke wehe i ka pena epoxy, epoxy zinc yellow primer, a maikaʻi loa no ka pena ʻili mokulele.

ʻO ka ʻoihana ʻoihana ʻo Mit-ivy he mea hana ʻoihana paʻi pena, ʻoi aku ka maikaʻi o ke kaiapuni a me ka maikaʻi. Welina mai e kelepona mai iā mākou: 86 138 05212761, linkedin:8613805212761 facebook:8613805212761
