Ukuthandwa kweengxowa ezilukiweyo

Abathengi abaninzi ngewebhusayithi yethu ukuya kwiingcebiso zomnxeba malunga nokuthandwa kweentlobo zebhegi elukiweyo, ke namhlanje i-DongLai elukiweyo ibhegi uXiaobian ukucacisa ukuthandwa kweentlobo zeebhegi ezilukiweyo.

Iintlobo zeengxowa ezilukiweyo

Iingxowa ezilukiweyo zikwabizwa ngokuba ziingxowa zesikhumba senyoka. Luhlobo lweplastiki, ikakhulu esetyenziselwa ukupakisha. Izinto ekrwada ngokubanzi i-polyethylene, i-polypropylene kunye nezinye iikhemikhali zeplastiki imathiriyeli ekrwada. Nantsi intshayelelo emfutshane yohlobo lwengxowa elukiweyo kunye nokusetyenziswa.

I-polyethylene iyona nto iphambili yemveliso yangaphandle, i-polypropylene iyona mveliso iphambili yasekhaya. I-resin ye-thermoplastic eyenziwe nge-polymerization ye-ethylene. Kwishishini, ikwabandakanya i-copolymers ye-ethylene kunye nenani elincinci le-α-olefin. I-Polyethylene ayinavumba, ayinayo ityhefu, i-waxy, inokumelana nobushushu obuphantsi kakhulu (ubuncinci beqondo lobushushu bokusebenza ukuya kuthi ga -70 ~ -100 ℃), ukuzinza kweekhemikhali ezilungileyo, ukuxhathisa kwe-asidi kunye ne-alkali ye-corrosion (ukumelana ne-asidi, i-oxidation), i-insoluble kwi-solvents jikelele kwiqondo lobushushu begumbi, ukufunxwa kwamanzi aphantsi, ukusebenza kakuhle kombane wokugquma; Nangona kunjalo, i-polyethylene ivakalelwa kakhulu kwiingcinezelo zokusingqongileyo (iikhemikhali kunye neempembelelo zemishini) kwaye inokuchasana kakubi nokuguga kobushushu. Iipropati ze-polyethylene ziyahlukahluka kwiintlobo ezahlukeneyo, ngokukodwa kuxhomekeke kwisakhiwo se-molecular and density. Iindlela ezahlukeneyo zokuvelisa zinokuvelisa ukuxinana okuhlukeneyo (0.91-0.96g / cm3). I-Polyethylene inokucutshungulwa ngendlela efanayo ukuba iiplastiki eziqhelekileyo ze-thermoplastic zibunjwe (jonga iPlastiki processing). Isetyenziswe ngokubanzi kwimveliso yefilimu, izitya, iipayipi, ucingo olulodwa, ucingo kunye nekhebula, iimfuno zemihla ngemihla, njl. Ngo-1983, umthamo wehlabathi wemveliso we-polyethylene wawungama-24.65 eetoni ze-metric, kwaye isityalo esakhiwayo sasinomthamo we-3.16 yeetoni ze-metric.

Iipolypropylene (PP)

I-resin ye-thermoplastic eyenziwe nge-polymerization yepropylene. Kukho iintlobo ezintathu zolungelelwaniso, ezizezi, isotopic ngokupheleleyo, i-atactic kunye ne-indirect. Iimveliso zemizi-mveliso ziqulunqwe ikakhulu zizakhiwo ze-isotopic. I-Polypropylene iquka i-copolymer yepropylene kunye nenani elincinci le-ethylene. Ngokuqhelekileyo i-translucent, iqinile engenambala, ayinavumba kwaye ayinayo ityhefu. Ngenxa yemithetho yesakhiwo, i-crystallinity ephezulu, indawo yokunyibilika ukuya kuthi ga kwi-167 ℃, ukumelana nobushushu. Ngoxinaniso lwe-0.90g/cm3, yeyona plastiki ilula kakhulu. Ukumelana nokubola, amandla okuqina angama-30MPa, amandla, ukuqina kunye nokungafihli ngcono kune-polyethylene. Ububi bubushushu obuphantsi bokuchasana nefuthe elibi, kulula ukuguga, kodwa kunokuguqulwa kwaye kongezwe i-antioxidant ukoyisa.

Umbala webhegi elukiweyo umhlophe okanye ungekho mhlophe ngokubanzi, awunayo ityhefu kwaye awunancasa, ubungozi bomzimba womntu buncinci. Nangona zenziwe ngeendidi zeplastiki zeekhemikhali, kodwa ukukhuselwa okusingqongileyo okunamandla, amandla okuhlaziya;

Ibhegi elukiweyo isetyenziswa kakhulu, ikakhulu isetyenziselwa ukupakishwa kweempahla ezahlukeneyo, kwaye isetyenziswa kakhulu kushishino;

Isingxobo esilukiweyo sePlastiki esine-polypropylene resin njengesona sixhobo siphambili ekrwada, i-extrusion kunye noluleka kumsonto osicaba, emva koko ilukwe engxoweni.

Ingxowa yeplastiki ehlanganisiweyo ephothiweyo enelaphu elilukiweyo leplastiki njengesiseko semathiriyeli, ngokubumba ukuhamba.

Isetyenziselwa ukupakisha umgubo okanye izinto eziqinileyo zegranular kunye namanqaku aguqukayo. Ingxowa ehlanganisiweyo yeplastiki ephothiweyo yahlulwe ibe zimbini kwingxowa enye kwaye ezintathu kwingxowa enye ngokwendlela yokwenziwa kwezinto eziphambili.

Ngokwendlela yokuthunga, inokuthi ihlulwe ibe yingxowa ephantsi yokuthunga, isikhwama sokuthunga esisezantsi, isikhwama sokufaka kunye ne-glue-coated-coated.

Ngokuxhomekeke kububanzi obusebenzayo besikhwama, inokwahlulwa ibe yi-450, 500, 550, 600, 650 kunye ne-700 mm. Iinkcukacha ezikhethekileyo ziya kuvunyelwana ngazo omabini amaqela.

Ngaphezulu kukuthandwa kokwenza okuncinci kuzo zonke iintlobo zokugqitywa kwebhegi elukiweyo enxulumene nokubonisana, ngokwabelana ngomxholo, ukuya ekwazisweni kweentlobo zebhegi ezilukiweyo zinengqiqo ethile, ukuba ufuna ukungena nzulu kwisingxobo solwazi lwentengiso, ungaqhagamshelana nomthengisi kwinkampani yethu, okanye empuma kunye nebhegi elukiweyo kwindawo yophando, olu nxibelelwano lwephepha luyaxoxwa.
