Mutsetse wekuwedzera wepaipi weHDPE unochengetedza simba nekukurumidza

Tsvagiridzo yazvino yekambani yedu uye kuvandudzwa kwemutsara wekugadzira unochengetedza simba nekukurumidza, wakakodzera kuburitsa pombi yepolyolefin inokurumidza. Kuchengetedza simba kwe35% uye kuwedzera kwekushanda zvakanaka kwekugadzira. Chimiro chescrew chakagadzirwa ne38-40 L/D uye feeding slot bar zvinoita kuti extrusion inonyungudika uye plasticizing ive nani zvikuru. Mabhokisi egiya ane torque yakakwirira, ane simba guru anovimbisa kushanda kwakasimba kwemidziyo. Makumbo eextrusion nemasleeve ehukuru anotevedzera dhizaini yepamusoro-soro. Tangi re PLC variable frequency control vacuum, servo-driven multi-track tractor, uye high-speed chip-less cutter zvine system yekudzora uremu hwemita. Huremu hweextrusion yepombi hwakarurama.

Pombi yeHDPE ipombi yepurasitiki inochinjika yakagadzirwa nepolyethylene ine thermoplastic yakawanda inoshandiswa zvakanyanya kutakura mvura inonwiwa, marara ane njodzi, magasi akasiyana-siyana, matope, mvura yemoto, mvura yemvura, nezvimwewo. Kubatana kwakasimba kwemamorekuru epombi yeHDPE kunobatsira kuti ishandise pamapaipi ane simba guru. Mapaipi epolyethylene ane nhoroondo refu uye inozivikanwa yebasa remagasi, mafuta, migodhi, mvura, nemamwe maindasitiri. Nekuda kwehuremu hwayo hushoma uye kuramba ngura kwakanyanya, indasitiri yemapaipi eHDPE iri kukura zvikuru. Mugore ra1953, Karl Ziegler naErhard Holzkamp vakawana polyethene ine simba guru (HDPE). Mapaipi eHDPE anogona kushanda zvinogutsa munzvimbo dzakasiyana-siyana dzekupisa kubva -2200 F kusvika +1800 F. Zvisinei, kushandiswa kweMapaipi eHDPE hakukurudzirwi kana tembiricha yemvura ichipfuura 1220 F (500 C).

Mapaipi eHDPE anogadzirwa ne polymerization ye ethylene, chinhu chinobva mumafuta. Zvimwe zvinhu zvinowedzerwa (zvinosimbisa, zvinozadza, zvinopfavisa, zvinonyorovesa, mafuta anozora, zvinodzora marara, zvinobvisa moto, zvinoputira, zvinosanganisa, zvinoderedza marara e ultraviolet, nezvimwewo) zvinowedzerwa kuti pave nepaipi yekupedzisira yeHDPE nezvikamu zvayo. Kureba kwepaipi yeHDPE kunogadzirwa nekupisa resin yeHDPE. Inobva yaburitswa kuburikidza ne die, iyo inosarudza dhayamita yepaipi. Ukobvu hwemadziro epaipi hunotsanangurwa nekubatanidzwa kwehukuru hwe die, kumhanya kwe screw, uye kumhanya kwe tarakita inobviswa. Kazhinji, 3-5% kabhoni nhema inowedzerwa kuHDPE kuti irambe UV, izvo zvinoshandura mapaipi eHDPE kuita matema muruvara. Mamwe mavara akasiyana anowanikwa asi haawanzo shandiswa. Paipi yeHDPE ine mavara kana mitsetse inowanzova 90-95% dema, uko mutsetse wemavara unopihwa pa5% yekunze.
