Dab tsi yog Precast Concrete Magnet?
Precast qhob hlau nplaum (PC fixing magnetic boxes) yog ib qho tsim nyog siv thiab kev siv cuab yeej los ntawm kev txhim kho formwork mus rau hauv txaj hauv txaj ntawm qhov ntau hauv precast, xws li phab ntsa, kem.
Hlau nplaum:
Lawv tau ua los ntawm cov khoom tsis tshua zoo xws li neodymium hlau nplaum (feem ntau N42 los yog N45), uas muab cov khoom zoo dua li lwm cov khoom siv hlau nplaum. Cov hlau nplaum raug tsim kom cov hlau nplaum fais fab tuag nrog cov hlau kom sib kis tau qhov sib nqus ntawm qhov sib nqus thiab ua rau thaj chaw sib cuag.
Cov hlau nplaum thiab hlau phom raug muab xauv thiab sib txuas ua ke los ntawm ib txoj hlua hlau uas tsis txhuam los ntawm qhov ntawm cov hlau nplaum thiab hlau.
Dua:
Cov chaw nyob puag ncig lub hlau nplaum los tiv thaiv kev puas tsuaj, los yog hlau yuav raug siv los coj tus xauj tsev mus rau cov hlau nplaum.
1. Q235A feem ntau, piv nrog cov hlau tsis muaj steel, nws qhov teebmeem magnetic flux generated yog zoo dua qub thiab nws cov nqi ntau dua.
2. Kev tiv thaiv xeb ntawm hlau thaiv , tha xim thiab dub. Thaum painting saum npoo yog yooj yim rau khawb thiab poob tawm. Yog li feem ntau blackening yog zoo dua.
3. Hlau tsis muaj stainless : ntau nqi tshaj hlau, tab sis stainless yog ntau thiab ntau nrov nyob rau hauv kev ua lag luam, vim hais tias hlau hom tej zaum yuav rusted, tom qab lub sij hawm ntawm kev siv.
Kev kho mob yuav tsum tau noj thaum siv cov hlau nplaum kom lub hauv paus huv thiab dawb los ntawm khib nyiab. Cov khib nyiab no ua rau poob ntawm lub zog vim muaj huab cua loj tuaj nruab nrab ntawm cov hlau nplaum thiab lub txaj.
