一, Chlorinated polyethylene (CPE) ipurasitiki yakagadzirwa ne chlorination substitution reaction ye high-density polyethylene (HDPE), uye huwandu hwe chlorine hwayo hunowanzova pakati pe25% ne45%. Iyi purasitiki inosanganisa simba rayo uye rabha, uye mashandiro ayo anoratidza hunhu hwakasiyana nemazinga akasiyana e chlorination:
1. Kuwanda kwechlorine (25% -35%): Kupfava kwakanyanya, kwakakodzera kugadziriswa kwerabha;
2. Kuwanda kwechlorine pakati nepakati kusvika pakakwirira (35% -45%): Inobatanidza kuchinjika uye kuomarara uye inowanzoshandiswa muzvinhu zvinodzora moto.
Nzvimbo huru dzekushandisa
1. Waya netambo
Chishandiso chemugodhi chinoshandiswa patambo dzemugodhi wemarasha netambo dzeUL/VDE dzinochengetedza kuchengetedzeka kwemagetsi uye kugadzikana, dzichidzivirira kupisa kwakanyanya uye dzinodzora moto.
2. Indasitiri yemotokari
Kugadzira mahosi ehydraulic, mahosi emotokari, uye wire harness sheaths dzinogona kutsungirira tembiricha yakaderera ye -30 ℃ uku dzichiramba dzakasimba.
3. Zvishandiso zvekuvaka
Sechivharo chekuvhara magonhi nemahwindo uye chinogadzirisa mapaipi, chinoshandisa zvakanakira kusapinda kwemamiriro ekunze uye kugadzikana kwemakemikari.
4. Zvigadzirwa zvemaindasitiri
Zvinoshandiswa patepi, pepa rinonamira, zvinhu zvine magineti, uye kugadzirisa ABS/PVC kuti chigadzirwa chiwedzere hunhu hwemakanika uye kuramba kukwegura.
5. Minda yakakosha
Sangana nezvinodiwa zvekudzivirira ngura yemakemikari zvemidziyo yemakemikari inodzivirira ngura, zvikamu zvengarava nezvimwe zviitiko.
Hunhu hweCPE hwezvakatipoteredza (husina chepfu uye husina hwema) uye chitupa cheUL94-V0 chinodzivirira moto zvinoita kuti ive mutambi akakosha muminda yekugadzira girini uye zvinodiwa zvekushanda kwepamusoro.
