Polyethylene sleeve: maitiro, kushandiswa

Mhando dzakawanda kwazvo dzepurasitiki dzakagadzirwa nehuwandu hwepeyetetheni. Iko kunogadzirwa kubva pamapuranga anozivikanwa-T-shati, uye zvinhu zvekugadzira michina. Zvisinei, maererano nekutaridzika, sarudzo yakanakisisa isaga-sleeve. Zvigaro zvaro zvinosanganisira kushandiswa kwezvinhu zvakasiyana-siyana. Izvi zvinoreva kuti nenzira imwe neimwe, mudzidzi pachedu anogona kusiyanisa zvigadziridzo. Panguva imwecheteyo, sleeve yepa polyethylene inochengetedza zvinyorwa zvose zvepakatikeji, iyo inosanganisira simba, nyore kugadzirisa uye kusimba.

Iko kupi sleeve ye polyethylene inoshandiswa?

Iyi firimu ndiyo chikonzero chekuwedzera kwekugadzira mabhegi. Nokudaro, inogona kunzi nyika yose. Iyo hose inogona kuita sechinhu chinoshandiswa mumashandisi ekugadzira, pakupa zvekuchengetedza mabhizimusi, uye mumhuri. Sezvo mutemo, bhuti re polyethylene yekuputira rinoshandiswa apo rinofanirwa kushanda nemagetsi akawanda emuchina kana chigadzirwa. Somuenzaniso, kutakura zvinhu zvisina kusimba. Kusava nekutaura kwemafuro uye kushandiswa kunobvumira kugadzira mitsara yokugadzirisa inogadziriswa, iyo isingadi kubudiswa kwevashandi.

Iyi firimu inoshandiswa nenzira yesimbi uye mune dzimwe nzvimbo dzakasiyana. Saka, pane polyethylene, yakagadzirwa kuti ishandiswe mune zvigetsi zvemagetsi. Nekubatsira kwepakati yakadaro iwe unogona kuparadzanisa zvigadzirwa nemagetsi, unozvidzivirira kubva pakusviba. Imwe michina ye polyethylene yemichero inowanzonyoresa, iyo inoda kuti zvidimbu zvive zvakagadzirwa maererano nehupenyu hwakachena.

Manufacturing teknolojia

Zvakare, polyethylene inotanga kuva chinhu chakagadzirwa pakugadzira zvikwama zvine mashizha uye zvimwe zvakagadzirirwa kana mudzimba. Iyo hose, zvakare, inobva pane imwe nzira yekuwana firimu refirimu. Pamusana pekugadzirwa kwayo, plastiki granules inoshandiswa nehumwe unhu hunhu. Mukudengenyeka, sleeve yema polyethylene inoumbwa kuitira kuiswa mufananidzo wefirimu. Mune ramangwana, vashandi vanogona kupatsanura mupumburu kuita zvidimbu, vachigadzira chigadzirwa chakati-kupera kwepakisi yakakwana neyekubata.

Kuti kuwedzere simba, vashandi vanowedzerawo zvimwe zvinowedzera, plasticizers uye zvinoshandiswa pakugadzirwa kwekutanga. Somugumisiro, sleeve ye polyethylene inowedzera simba rakasimba. Uyewo, nzira yekugadzira inogona kusanganisira kudhinda nekugadzira rebate inoiswa. Asi mabasa akadaro, sekutonga, anoitwa pasi pemirairo inokosha.

Mamiriro

Kureba kwepakoti kazhinji hakusi kusarudzwa - sleeve inosunungurwa zvachose. Kana iri hupamhi, maitiro akajairika ari 20, 30 uye 40 cm, kunyange zvichienderana nehutano hwemidziyo, urongwa hwekukura hunogona kuwedzera. Uwandu hwemafirimu akawanda huri pakati pe 30-200 microns. Pasinei nehutano hwakanaka, sleeve ye polyethylene inogona kumira mitoro inorema - makumi masere e kilogiramu. Zvakakosha kuti zvinhu zvakagadzirwa kubva kune secondary polyethylene zvine mazamu akawanda, izvo zvinokonzerawo simba rakasimba.

Basa remufirimu

Sezvatatoona, michina yehutongi ye polyethylene yakagadzirirwa zvikuru zvidimbu nezvimwe zvinowedzera, zvinowanikwa mukugadzirwa kwemhando. Kunyanya, kushandura modifiers kunopa mashoko echese coefficient of friction. Izvi zvinonyorera kuvhura kwejasi, inopa firimu chimwe chinhu chinonzi gloss, asi panguva imwechete inobvisa kuitika kwechimiro. Zvimwe zvinopesana nezvisungo zvinoshandiswawo zvakananga kudzivirira mukati mamasvingo ezvinyorwa kubva pamwe chete. Nekuwedzera uku, firimu haisi kungobvisa kukanganisa, asiwo inowedzera kuoma kwezvisikwa. Nzira yekupa kunze kudzivirirwa yakapararirawo, iyo inowedzera nefirimu ye polyethylene. Iyo sleeve, mukugadziriswa kwekutsvaira moto kwakashandiswa, somuenzaniso, inopesana nemoto. Icho chirevo chekudzimisa moto chinowanikwa kuburikidza nekuiswa kwezvinyorwa zvakasara zvakanyora, izvo zvinoumba gontaceous layer. Somugumisiro, chipingamupinyi chinopesana chinoumbwa, icho chinodzivirirawo kusunungurwa kwezvinhu zvakashata panguva yekupisa.

Mutengo wezvinhu

Kazhinji vadziri vanogadzira matengo pachavo, vachitarisa pamiganhu yeimwe chirongwa. Mari yacho inoshandiswa nehupamhi hwechando, uye hutema, pamwe chete nemitambo inoshandiswa nefirimu ye polyethylene. Mutengo wemapumburu nehupamhi hwemasendimita makumi maviri nemakumi mashanu kusvika pamakumi mashanu pahuwandu ndewe 180-200 rubles pa 1 kg. Uhu hunogona kuenzana kubva pa40 kusvika ku 120 μm. Firimu yakawanda yakawanda inogona kuwedzera mutengo nemamwe ruble makumi mashanu. Per kilogram, asi pano zvakanyanya zvinoenderana nehuwandu hwehutano.

Zviduku zvakagadzirwa nemidziyo zvakaparidzirwa nenzira yemasleeve ane upamhi hwema 6 kusvika ku15 cm Nekubatsira kwefirimu yakadaro, zvikwata zviduku zvingatangwa zvinogona kuumbwa munzvimbo dzekudya zvepaguru. Zvisinei, pane dzakawanda mabhizimusi emabhizimisi umo madiki-mafirimu epa polyethylene firimu inoshandiswa. Mutengo munyaya ino watove 250-300 rubles pa 1 kg. Kuwedzera kwemari kunokonzerwa nekuoma kwebasa rekuita mapeiri nehuwandu hudiki.

Mhedziso

Kushandisa mazano anobatsira akaitwa ne polyethylene, zvinogona kugovera kuchengetedzwa kwemagetsi kwechigadzirwa, uye kuchidzivirira kubva pamigumisiro yekushisa kwakanyanya uye kunaya. Panguva imwecheteyo, teknolojia inoshingaira kuwana hutsva hunoita hutsika hwezvinhu zvakagadziriswa nekuvandudzwa kwemashandisi. Kunyanya, kana iwe uronga kushandisa sleeve yepa polyethylene munzvimbo dzinotaridzika kune chiedza chezuva, iwe unofanirwa kubhadhara pane zvinyorwa zvekugadzirisa chiedza. Saka, kana iyo firimu inotengwa kuti ifukidze kupisa, ipapo zuva rakazaruka harizokuvadza kupfeka kusinga kupisa. Mukutaura, kuitira kuti urambe uine simba uye simba pasi pemamiriro ekudzikira akaderera, firimu ine frost-resistant additives inofanira kushandiswa.
