ʻO ka hose, kahi mea hoʻopihapiha kūpono a me ka waiwai, hoʻohana nui ʻia i ke kahua o nā kemika i kēlā me kēia lā a kaulana loa. ʻAʻole hiki i ka hose maikaʻi ke pale wale i nā mea i loko, akā hoʻomaikaʻi pū i ka pae huahana, no laila e lanakila ai nā mea kūʻai aku no nā ʻoihana kemika i kēlā me kēia lā. No laila, no nā hui kemika i kēlā me kēia lā, pehea e koho aikiʻekiʻe kiʻekiʻe-koʻikoʻi paipui kūpono i kā lākou huahana?
ʻO ke koho a me ka maikaʻi o nā mea waiwai ke kī i ka hōʻoia ʻana i ka maikaʻi o nā hoses, e hoʻopili pololei i ka hana a me ka hoʻohana hope ʻana i nā hoses. ʻO nā mea hana o nā paipu plastik he polyethylene (no ke kino paipu a me ke poʻo o ka paipu), polypropylene (ka uhi pahu), masterbatch, pale resin, ka inika paʻi, varnish, a me nā mea ʻē aʻe. Eia nō naʻe, ʻo ke koho ʻana o nā mea e pili ana i nā mea e like me nā koi o ka maʻemaʻe, nā waiwai pale (koi no ka oxygen, wai mahu, mālama ʻala, a me nā mea ʻē aʻe), a me ke kūpaʻa kemika.
Ke koho ʻana i nā paipu: ʻO ka mea mua, pono nā mea i hoʻohana ʻia e kūpono i nā kūlana maʻemaʻe kūpono, a pono e hoʻomalu ʻia nā mea ʻino e like me nā metala kaumaha a me nā mea fluorescent i loko o ka pae i kuhikuhi ʻia. No ka laʻana, no nā paipu i lawe ʻia aku i ʻAmelika Hui Pū ʻIa, pono ka polyethylene (PE) a me ka polypropylene (PP) i hoʻohana ʻia e hoʻokō me ka US Food and Drug Administration (FDA) standard 21CFR117.1520.
ʻO nā mea pale o nā mea waiwai: Inā ʻo nā mea i loko o ka ʻeke o nā hui kemika i kēlā me kēia lā kekahi mau huahana e pili pono ana i ka oxygen (e like me kekahi mau mea hoʻonaninani keʻokeʻo) a i ʻole ke ʻala ʻala (e like me nā aila pono a i ʻole kekahi mau aila, nā waikawa, nā paʻakai a me nā paʻakai. nā mea ʻino ʻē aʻe), pono e hoʻohana ʻia nā paipu co-extruded ʻelima i kēia manawa. No ka mea, ʻo ka oxygen permeability o ka ʻelima-layer co-extruded tube (polyethylene / adhesive resin / EVOH / adhesive resin / polyethylene) he 0.2-1.2 mau ʻāpana, ʻoiai ka oxygen permeability o ka polyethylene one-layer tube maʻamau he 150-300 mau ʻāpana. I kekahi manawa, ʻoi aku ka haʻahaʻa o ka nui o ka pohō kaumaha o ka paipu co-extruded i loko o ka ethanol ma mua o ka nui o ka paipu hoʻokahi. Eia kekahi, ʻo EVOH kahi ethylene-vinyl alcohol copolymer me nā waiwai pale maikaʻi a me ka paʻa ʻana o ka ʻala (loaʻa ka hopena maikaʻi loa inā ʻo 15-20 microns ka mānoanoa).
ʻO ke koʻikoʻi o nā mea: He ʻokoʻa nā koi o nā hui kemika i kēlā me kēia lā no ka paʻakikī o nā hoses, no laila pehea e loaʻa ai ka ʻoʻoleʻa i makemake ʻia? ʻO ka polyethylene i hoʻohana mau ʻia i loko o nā hoses ka nui o ka polyethylene haʻahaʻa haʻahaʻa, polyethylene kiʻekiʻe kiʻekiʻe, a me ka polyethylene haʻahaʻa haʻahaʻa laina. I waena o lākou, ʻoi aku ka maikaʻi o ka polyethylene kiʻekiʻe kiʻekiʻe ma mua o ka polyethylene haʻahaʻa haʻahaʻa, no laila hiki ke hoʻokō ʻia ka paʻakikī i makemake ʻia ma ka hoʻoponopono ʻana i ka ratio o ka polyethylene kiʻekiʻe / haʻahaʻa haʻahaʻa.
Ke kū'ē kemika o nā mea waiwai: 'Oi aku ka maika'i o ka pale kemika ma mua o ka polyethylene ha'aha'a.
Ke kū'ē i ka wā o nā mea waiwai: No ka mālamaʻana i ka hana pōkole a lōʻihi paha o nā hoses, nā mea e like me keʻano, ke kū'ē i ke kaomi / hoʻokuʻuʻana i ka hana, ka ikaika hoʻopaʻa paʻa, ke kū'ēʻana i ka pilikia o ka nohona (ESCR waiwai), ka meaʻala a me ka nalowale o nā mea hana pono e pono. e noonooia.
Ke koho ʻana i ka masterbatch: He kuleana koʻikoʻi ka Masterbatch i ka mana o ka maikaʻi o nā hoses. No laila, i ke koho ʻana i ka masterbatch, pono e noʻonoʻo nā ʻoihana mea hoʻohana inā he maikaʻi ka dispersibility, kānana a me ke kūpaʻa wela, ke kū ʻana o ka wā a me ke kūpaʻa huahana. I waena o lākou, he mea koʻikoʻi ka pale ʻana o ka huahana masterbatch i ka wā o ka hoʻohana ʻana i nā hoses. Inā kūpono ʻole ka masterbatch me ka huahana i loko, e neʻe ke kala o ka masterbatch i loko o ka huahana, a he koʻikoʻi loa nā hopena. No laila, pono nā hui kemika i kēlā me kēia lā e hoʻāʻo i ka kūpaʻa o nā huahana hou a me nā hoses (nā hoʻokolohua wikiwiki ma lalo o nā kūlana i kuhikuhi ʻia).
ʻO nā ʻano varnish a me kā lākou mau hiʻohiʻona: Hoʻokaʻawale ʻia ka varnish i hoʻohana ʻia no nā hoses i ke ʻano UV a me ke ʻano maloʻo wela, hiki ke hoʻokaʻawale ʻia i ka ʻili kukui a me ka ʻili matte i ka helehelena. ʻAʻole hāʻawi wale ʻo Varnish i nā hopena hiʻohiʻona nani, akā pale pū nō hoʻi i nā ʻike a loaʻa kekahi hopena o ka pale ʻana i ka oxygen, ka wai wai a me ka ʻala. Ma ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o ka hoʻomaloʻo ʻana i ka ʻano varnish i ka hoʻopaʻa ʻana i ka wela a me ka paʻi kilika, ʻoiai ʻoi aku ka maikaʻi o ka varnish UV. Hiki i nā hui kemika i kēlā me kēia lā ke koho i ka varnish kūpono e like me nā ʻano o kā lākou huahana. Eia kekahi, pono i ka varnish i ho'ōla ʻia ke adhesion maikaʻi, ka ʻili maʻemaʻe me ka ʻole o ka lua, ka pale ʻana i ka pale ʻana, ke kūpaʻa ʻana, ka pale ʻana i ka corrosion, a ʻaʻohe discoloration i ka wā mālama.
Nā mea e pono ai no ke kino paipu.
1. Pono ka ili o ke kino paipu me ka lauwili ole, me ke kaha ole, ke ku'i, a me ka hoemi ana. Pono ke kino paipu pololei a ʻaʻole piʻo. Pono ka mānoanoa o ka pā paipu. Pono ka mānoanoa o ka pā paipu, ka lōʻihi o ka paipu, a me ke anawaena i loko o ka laulā i ʻōlelo ʻia;
2. Pono e hoʻopili paʻa ʻia ke poʻo o ka paipu a me ke kino o ka paipu, ʻo ka laina hoʻopili pono e maʻemaʻe a nani hoʻi, a ʻo ka laulā ke ʻano like. ʻAʻole pono e skewed ke poʻo paipu ma hope o ka hoʻopili ʻana;
3. Pono ke po'o o ka paipu a me ka uhi o ka paipu, e wili i loko a i waho me ka ma'alahi, a 'a'ole pono e pahe'e i loko o ke kaha o ka torque i ho'ākāka 'ia, a 'a'ole e kahe ka wai a me ka ea ma waena o ka paipu a me ka uhi;
Nā koi paʻi: Hoʻohana pinepine ʻia ka hose hose i ka lithographic offset printing (OFFSET), a ʻo ka hapa nui o ka inika i hoʻohana ʻia he UV-maloʻo, ʻo ia ka mea e koi ai i ka hoʻopili ikaika a me ke kūpaʻa ʻana i ka discoloration. Pono ka waihoʻoluʻu paʻi i loko o ka laulā hohonu i ʻōlelo ʻia, pono ke kūlana overprint, pono ka deviation i loko o 0.2mm, a ʻo ka font pono e piha a maopopo.
Nā koi no nā pāpale plastik: Hana mau ʻia nā pāpale plastik me ka polypropylene (PP) injection molding. ʻAʻole pono e loaʻa i nā pāpale plastik kūlana kiʻekiʻe nā laina hōʻemi a me ka uila, nā laina ʻeleʻele maʻemaʻe, nā ana pololei, a me ka maʻalahi me ke poʻo paipu. ʻAʻole pono lākou e hoʻopōʻino i ke kino e like me nā māwae brittle a i ʻole nā māwae i ka wā hoʻohana maʻamau. No ka laʻana, i ka wā o ka ikaika wehe i loko o ka laulā, hiki i ka pāpale flip ke kūpaʻa ma mua o 300 paʻi me ka haki ʻole.
Ke manaʻoʻiʻo nei au e hoʻomaka ana mai nā ʻano i luna aʻe, hiki i ka hapa nui o nā hui kemika i kēlā me kēia lā ke koho i nā huahana hose packaging kiʻekiʻe.
