Ndi kukula kwakukulu / kwakukulu kwa ulimi wa nkhuku, alimi ambiri a nkhuku amasankhakuyala nkhuku kholaulimi chifukwa ulimi khola uli ndi ubwino zotsatirazi:
(1) Wonjezerani kuchuluka kwa masheya.Kachulukidwe ka makola a nkhuku amitundu itatu ndi okwera katatu kuposa a khola lathyathyathya, ndipo nkhuku zopitilira 17 zimatha kukwezedwa pa lalikulu mita;
(2) Sungani chakudya.Nkhuku zimasungidwa m'makola, kuchuluka kwa masewera olimbitsa thupi kumachepetsedwa, mphamvu zogwiritsira ntchito mphamvu zimakhala zochepa, ndipo kutaya kwa zinthu kumachepetsedwa.Kukhazikitsa ubereki wochita kupanga kungachepetse kuchuluka kwa atambala;
(3) Nkhuku sizikumana ndi ndowe, zomwe zimathandiza kupewa mliri wa ziweto;
(4) Mazirawa ndi aukhondo, amene amatha kuchotsa mazira kunja kwa chisa.
Komabe, alimi ambiri sadziwa processing luso lamakola a nkhuku.Angasankhe bwanji khola la nkhuku zabwinobwino komanso moyo wautali?Mu zida zoweta nkhuku zokha, kusankha makola a nkhuku ndikofunikira kwambiri ngati kukhudzana mwachindunji ndi nkhuku.Pakadali pano, pali mitundu inayi ya makola pamsika omwe alimi a nkhuku angasankhe:
1. Kuzizira malabati.
Cold galvanizing, yomwe imadziwikanso kuti electrogalvanizing, imakhala ndi gawo lochepa la malata.Ubwino wa galvanizing ozizira ndi yosalala pamwamba ndi mkulu kuwala;Komabe, nthawi zambiri amagwiritsidwa ntchito kwa zaka 2-3 kuti achite dzimbiri ndipo amakhala ndi zaka 6-7.Cold galvanizing akhoza kugawidwa mu kanasonkhezereka Mtundu zinki kapena woyera nthaka, etc., zotsatira ndi ofanana.
2. Kutentha kwa dip galvanizing.
Hot-dip galvanizing, yomwe imadziwikanso kuti hot-dip galvanizing, makulidwe a malata nthawi zambiri amakhala oposa 80.μm kuonedwa kuti ndi oyenerera, nthawi zambiri n'kosavuta dzimbiri, mkulu dzimbiri kukana, zambiri angagwiritsidwe ntchito kwa zaka 15 mpaka 20, koma kuipa ndi galvanizing mu galvanizing dziwe Osafanana, chifukwa mu burrs ambiri, amene amafuna pamanja processing mu pambuyo pake.Kutentha-kuviika kanasonkhezereka nkhuku makolandi kusankha koyamba pa ulimi wodzichitira okha, koma mtengo wake nthawi zambiri umakhala wokwera kuposa ena.
3. Utsi pa khola la nkhuku.
Chophimba cha ufa chimakokedwa ndi khola chifukwa cha mphamvu yamagetsi yamagetsi yamagetsi, ndikupanga filimu yolimbana ndi dzimbiri ya phosphating pakati pa khola la nkhuku ndi zokutira, koma khola la nkhuku lopopera ndilosavuta kumamatira ku manyowa a nkhuku, sizidzakhala zophweka kwa nthawi yaitali.Ndi yosavuta kukalamba ndi kugwa.Khola la nkhuku zotere ndi losowa kwambiri pamsika, ndipo msika ndi wochepa.
4. Zinc aluminium alloy nkhuku khola.
Zinc-aluminiyamu alloy waya amagwiritsidwa ntchito kuwotcherera mwachindunji, ndipo palibe kukonzanso kwina komwe kumafunika pambuyo pake.Zofunikira zowotcherera zamtundu uwu wa khola la nkhuku ndizokwera kwambiri.Ngati kuwotcherera sikuli bwino, zolumikizira za solder zitha dzimbiri.Ngati ndondomekoyi ikugwiritsidwa ntchito bwino, moyo wautumiki udzafika zaka zoposa 10.Zida zambiri zotumizidwa kunja zimagwiritsa ntchito mauna amtunduwu.
Pankhani ya kulimba, kutentha-kuviika galvanizing> zinki-aluminiyamu aloyi> kupopera mbewu mankhwalawa> galvanizing ozizira.
Tsatirani ife tidzasintha zambiri zoswana.
