Ukupakisha Ukuthengwa Kwezinto Ezibonakalayo | Ungayikhetha Kanjani Imikhiqizo Ye-Plastical Hose ephezulu

Ukukhethwa kanye nekhwalithi yezinto zokwakha kuyisihluthulelo sokuqinisekisa ikhwalithi yama-hoses, okuzothinta ngqo ukucubungula nokusetshenziswa kokugcina kwama-hoses. Izinto zokwakha ama-hoses zepulasitiki zifaka i-polyethylene (yomzimba weshubhu nekhanda le-tube), i-polypropylene (i-cartier resin) Kodwa-ke, ukukhethwa kwezinto zokwakha nakho kuncike ezintweni ezifana nezidingo zokuhlanzeka, izidingo zomgoqo (izidingo zomoya-mpilo, umphunga wamanzi, ukulondolozwa kwamakha, kanye nokumelana kwamakhemikhali.

Ukukhethwa kwamapayipi: okokuqala, izinto ezisetshenzisiwe kufanele zihlangabezane namazinga okuhlanzeka afanele, nezinto eziyingozi ezifana nezinsimbi ezisindayo kanye nama-fluorescent agents kufanele alawulwe ngaphakathi kwebanga elibekiwe. Isibonelo, ama-hoses athunyelwa e-United States, i-polyethylene (pe) ne-polypropylene (PP) esetshenzisiwe kumele ahlangane ne-US Food and Drug Administration (FDA) Standard 21cfr117.1520.

Izakhiwo ezibanda kakhulu zezinto zokwakha: Uma okuqukethwe kokufakwa kwezinkampani zamakhemikhali nsuku zonke yiminye imikhiqizo ezwela kakhulu i-oksijini (njengezimonyo ezimhlophe) noma amakha athile athambile kakhulu (njengamafutha athile, ama-acid, usawoti kanye Amanye amakhemikhali awonakele), amashubhu ahlanganisiwe ahlanganisiwe kufanele asetshenziswe ngalesi sikhathi. Ngenxa yokuthi i-oxygen mpornical ye-tube ehlanganisiwe ye-exter extren Esikhathini esithile, isilinganiso sokunciphisa isisindo seshubhu elihlanganisiwe eliqukethe i-ethanol izikhathi eziningi eziphansi kunalezo zeshubhu elilodwa leleyili. Ngaphezu kwalokho, u-Evoh ungotshwala we-ethylene-vinyl okotshwala eCopolymer enezakhiwo ezinhle kakhulu zokuvimba kanye nokugcinwa kwamakha (ubukhulu baka-15-20 microns yiyona ehle kakhulu).

Ukuqina Kwezinto Ezibonakalayo: Izinkampani zamakhemikhali zansuku zonke zinezidingo ezihlukile zokuqina kwama-hoses, ngakho-ke ungakuthola kanjani ukuqina okufunayo? I-polyethylene esetshenziswa kakhulu kuma-hoses ikakhulukazi i-polyethylene ephansi, i-polyethylene ephezulu, kanye ne-polyethylene ephansi. Phakathi kwazo, ukuqina kwe-polyethylene ephakeme ephezulu kungcono kunalokho kwe-polyethylene ephansi, ngakho-ke ukuqina okufiselekayo kungatholakala ngokulungisa isilinganiso se-polyethylene ephezulu / okuphansi kwe-polyethylene.

Ukumelana namakhemikhali wezinto ezibonakalayo

Ukumelana kwesimo sezulu kwezinto zokwakha: Ukulawula ukusebenza kwesikhashana noma isikhathi eside se-hose, izinto ezifana nokubukeka, ukumelana nengcindezi / ukumelana nokuvimba ukumelana, inani le-Encrosoft yokuqhekeka) okufanele kubhekwe.

Ukukhetha kwe-Masterbatch: I-Masterbatch idlala indima ebalulekile ekuphathweni kwekhwalithi ye-hose. Ngakho-ke, lapho ukhetha i-masterbatch, inkampani yabasebenzisi kufanele ibheke ukuthi ingabe inokuhlakazeka okuhle, ukungcola nokuqina okushisayo, ukumelana kwesimo sezulu kanye nokumelana nomkhiqizo. Phakathi kwazo, ukumelana nomkhiqizo kwe-masterbatch kubaluleke kakhulu ngesikhathi sokusebenzisa i-hose. Uma i-masterbatch ingahambisani nomkhiqizo, umbala we-masterbatch uzothuthela kumkhiqizo, futhi imiphumela imbi kakhulu. Ngakho-ke, izinkampani zamakhemikhali zansuku zonke kufanele zihlole ukuqina kwemikhiqizo emisha nama-hoses (izivivinyo ezisheshisiwe ngaphansi kwezimo ezibekiwe).

Izinhlobo zama-varnish kanye nezimpawu zazo ezisetshenzisiwe: I-varnish esetshenziswe ku-hose ihlukaniswe ngohlobo lwe-UV kanye nohlobo lokushisa, futhi ingahlukaniswa ibe yindawo ekhanyayo kanye ne-matte ebusweni ngokubukeka. I-varnish ayigcini nje ngokunikeza imiphumela emihle yokubuka, kepha futhi ivikele okuqukethwe futhi inomphumela othile wokuvimba umoya-mpilo, umphunga wamanzi kanye nephunga. Ngokuvamile, i-varnish eyomisa ukushisa inama-adhesion amahle ekunyatheliseni okushisayo okulandelayo kanye nokuphrinta kwesikrini sesilika, kuyilapho i-UV varnish ine-gloss gloss. Izinkampani zamakhemikhali zansuku zonke zingakhetha i-varnish efanelekile ngokuya ngezimpawu zemikhiqizo yazo. Ngaphezu kwalokho, i-varnish ekhethiwe kufanele ibe nokunamathela okuhle, indawo ebushelelezi ngaphandle kokuphamba, ukugoqa ukumelana, ukumelana nokudla, ukungahambisani nokugqwala, futhi akukho diadlination ngesikhathi sokugcina.

Izidingo ze-Tube Body / Tube Head: 1 Umzimba we-tube kufanele uqonde futhi ungagome. Ubukhulu bodonga lweshubhu kufanele bube umfaniswano. Ubukhulu bodonga lweshubhu, ubude be-tube, kanye nokubekezelelana kobubanzi kufanele kube phakathi kobubanzi obucacisiwe;

2 Ikhanda le-tube akufanele libekwe ngemuva kokuxhumana; I-3. Ikhanda le-tube nesembozo seshubhu kufanele lifane kahle, lingena futhi liphume kahle, futhi akufanele kube nokushona ngaphakathi kwe-torque ebekiwe, futhi akufanele kube namanzi noma ukuvuza komoya phakathi kwe-tube nesembozo;

Izidingo zokuphrinta: Ukusebenza kwe-hose kuvame ukusebenzisa ukuphrinta kwe-lithographic offset (offset), futhi iningi le-inki elisetshenzisiwe limisiwe, elivame ukudinga ukunamathela okuqinile kanye nokumelana nokwamukelwa. Umbala wokuphrinta kufanele ube ngaphakathi kobubanzi bokujula obucacisiwe, isikhundla esinqunyelwe kufanele sinembile, ukuphambuka kufanele kube ngaphakathi kwe-0.2mm, futhi ifonti kufanele liphelele.

Izidingo zamakhebhu epulasitiki: Izimboni zepulasitiki zivame ukwenziwa nge-polypropylene (PP) yokubumba kokubumba. Izimboni zepulasitiki ezisezingeni eliphakeme akufanele zibe nemigqa ye-shrinkage esobala kanye nemigqa yokubumba ebushelelezi, ubukhulu obunembile, nobukhulu obunembile nekhanda le-tube. Akufanele badale ukulimala kwesakhiwo okufana nokuqhekeka noma imifantu ngezikhathi zokusetshenziswa okujwayelekile. Isibonelo, lapho amandla okuvula engaphakathi kobubanzi, i-flip cap kufanele ikwazi ukubekezelela amafolda angaphezu kwama-300 ngaphandle kokuphuka.
