Kusunga Kugula Zinthu | Momwe mungasankhire pulasitiki wapamwamba kwambiri

Kusankhidwa ndi mtundu wa zinthu ndiye njira yowonetsetsa kuti ma hoses, omwe azikhudza mwachindunji pokonza ndi kugwiritsa ntchito hosese. Zinthu za hoses za pulasitiki zimaphatikizapo polyethylene (ya chubu thupi la chubu), polyplech, chotchinga, kusindikizidwa kwa zinthu zilizonse zomwe zingakhudze momwe muliri mwachindunji. Komabe, kusankha zinthu kumadaliranso zinthu monga ukhondo, zotchinga (zofunikira zamadzi, nthunzi zonunkhira, ndi mankhwala.

Kusankhidwa kwa mapaipi: Choyamba, zinthu zomwe zimagwiritsidwa ntchito kuyenera kukwaniritsa miyezo yaukhondo, komanso zinthu zovulaza monga zitsulo zolemera komanso zothandiza molumwa ziyenera kulamulidwa pamtundu wopatsidwa. Mwachitsanzo, chifukwa hosses inamtumiza ku United States, polyethylene (pe) ndi polypropylene (pp) iyenera kukwaniritsa chakudya cha US ndi mankhwala osokoneza bongo 21cfr11520.

Zotchinga zotchinga: Mankhwala ena owononga, machubu asanu-otambalala azigwiritsidwa ntchito panthawiyi. Chifukwa oxygen kukhazikika kwa chubu-isanu ya chubu (polyethylene / zomata / enoh / ma utoto) Munthawi inayake, kuchepa kwa chubu cholemera cha co-extlad omwe ali ndi ethanol ndi nthawi yotsika kwambiri kuposa momwe imakhalira ndi chubu chimodzi. Kuphatikiza apo, Engoh ndi vuto loledzera la ethylel-vinyll yotchinga bwino kwambiri komanso kusungirako zonunkhira (makulidwe a 15-20 ndi abwino kwambiri).

Kuumbika kwa zinthu: Makampani amasiku a tsiku ndi tsiku ali ndi zofunikira zosiyanasiyana kuuma kwa hoses, kotero momwe mungapezere kuuma komwe mukufuna? Polyethylene omwe amagwiritsidwa ntchito nthawi zambiri amagwiritsa ntchito ma roses makamaka otsika polyethylene, ochulukirapo-cynal polyethylene, komanso mzere wotsika polyethylene. Pakati pawo, kuuma kwa ma polyethylene ndibwino kuposa kutsika kotsika polyethylene, kotero kuti kuuma komwe mungafunike kumatheka chifukwa cha kuchuluka kwa polyethylene.

Zinthu zakumwa ndi mankhwala: Kuchulukitsa-kapamwamba polyethylene kuli ndi mankhwala osokoneza bongo kuposa otsika polyethylene.

Kukana ndi nyengo: Kuwongolera kanthawi kochepa kapena kwa nthawi yayitali monga kuwoneka, kukana mphamvu, kutsimikiza kwa chilengedwe, Kununkhira kwa chilengedwe), kuwonongeka kwa zosakaniza kuganiziridwa.

Kusankhidwa kwa Masterbatch: Masterbatch amatenga gawo lofunikira pakuwongolera payipi. Chifukwa chake, posankha Masterbatch, kampani yogwiritsa ntchitoyo iyenera kulingalira ngati ili ndi kuperekera bwino, kusokonekera kwanyengo, kukana nyengo ndi kukana kwa nyengo. Pakati pawo, kukana kwa masterbatch ndi kofunikira kwambiri panthawi yomwe amagwiritsa ntchito payipi. Ngati masterbatch sagwirizana ndi malonda, mtundu wa masterbatch isamukira pazogulitsa, ndipo zotsatirapo zake ndizovuta kwambiri. Chifukwa chake, makampani amtundu wa tsiku ndi tsiku ayenera kuyesa kukhazikika kwa zinthu zatsopano ndi ma hoses (mayeso achangu omwe amayesedwa pansi).

Mitundu ya varnish ndi mawonekedwe awo: The Farnish yomwe imagwiritsidwa ntchito mu payipi imagawidwa mu mtundu wa UV ndi Kutentha kwa kutentha, ndipo imatha kugawidwa pamwamba ndi matte pamwamba. Varnish Sikuti zimangopereka zowoneka bwino, komanso zimateteza zomwe zili mkati mwake ndipo zimathandizanso kutsekereza oxygen, madzi ampweya wamadzi ndi kununkhira. Nthawi zambiri, kufota kwa kutentha kumakhala ndi zotsatsa bwino mpaka kusindikizidwa kotentha ndi kusindikiza kwa silika, pomwe UV Varnish ili ndi gloss. Makampani tsiku lililonse mankhwala amatha kusankha varnish yoyenera molingana ndi zinthu zawo. Kuphatikiza apo, varnish yochiritsidwa iyenera kukhala ndi zomatira bwino, malo osalala osapitsira, kukana kukana, kuvala kukana, kuwonongeka kwa chipongwe, ndipo palibe chosakanikirana panthawi yosungirako.

Zofunikira za Thupi la Thupi / Tube mutu: 1. Pamwamba pa chubu chimayenera kukhala chosalala, chopanda malire, zikanda, zikanda, zoyipa, kapena kusinthitsa shringer. Thupi la chubu liyenera kukhala lowongoka ndipo siliri lolunjika. Khoma la chubu makulidwe ayenera kukhala yunifolomu. Khoma la chubu makulidwe, chubu kutalika, ndi kulolerana kochepera kuyenera kukhala mkati mwa mitundu yomwe yatchulidwa;

2. Mutu mutu suyenera kukhazikika pambuyo pa kulumikizana; 3. Mutu mutu ndi chivundikiro cha chubu muyenera kufanana, scress mkati ndi kunja, ndipo sipayenera kutsika mkati mwa torque lest, ndipo payenera kukhala wopanda madzi kapena kuyika kwa mpweya pakati pa chubu ndi chivundikiro;

Kusindikiza Kosankha: Kukonzekera kwa Hise nthawi zambiri kumagwiritsa ntchito kusindikiza kwa Liagrance Mtundu wosindikiza uyenera kukhala mkati mozama, mawonekedwe ochulukirapo ayenera kukhala olondola, kupatuka kuyenera kukhala mkati mwa 0,2mm, ndipo fint iyenera kukhala yokwanira.

Zofunikira za Zipangizo zapulasitiki: Zipangizo za pulasitiki nthawi zambiri zimapangidwa ndi polypropylene (ma pp) akuumba. Zipangizo zapamwamba za pulasitiki zokhala ndi pulasitiki siziyenera kukhala ndi mizere yowoneka bwino komanso zowoneka bwino, zowoneka bwino, zolondola, komanso zosalala bwino ndi mutu. Sayenera kuwononga zowonongeka monga ming'alu kapena ming'alu panthawi yogwiritsa ntchito bwino. Mwachitsanzo, mphamvu yotsegulira ili mkati mwake, chipewa cha Flip liyenera kupirira zopitilira 300 popanda kuphwanya.
