Emelitere na Nọvemba 2, 2022
Nke a bụ ebe akụkọ ụlọ ọrụ na-akpụzi ịgba ọgwụ mgbochi ọrịa Baiyear.Na-esote, Baiyear ga-ekewa usoro ịkpụzi injection n'ime ọtụtụ akụkọ iji webata nyocha nke akụrụngwa nke usoro ịkpụzi injection, n'ihi na enwere ọtụtụ ọdịnaya.Na-esote bụ edemede mbụ.
(1).PS (polystyrene)
1. Arụmọrụ nke PS:
PS bụ polymer amorphous nke nwere ezigbo mmiri na mmiri dị ala (ihe na-erughị 00.2%).Ọ bụ plastik transperent nke dị mfe ịmepụta na nhazi.Ngwaahịa ya nwere nnyefe ọkụ nke 88-92%, ike tinting siri ike na ike siri ike.Otú ọ dị, ngwaahịa PS na-agbaji agbaji, na-enwekarị nrụgide n'ime ime, na-enwe mmetụta na-adịghị mma nke okpomọkụ (60-80 ° C), na-adịghị egbu egbu, ma nwee nnukwu ike dị ihe dịka 1.04g \ cm3 (obere ntakịrị karịa mmiri).
Nhazi shrinkage (uru bụ n'ozuzu 0.004-0.007in / in), PS transperent - aha a na-egosi naanị nghọta nke resin, ọ bụghị kristal.(Chemical na anụ ahụ Njirimara: Ọtụtụ ahịa PS bụ transperent, amorphous ihe. PS nwere ezigbo geometric kwụsie ike, thermal nkwụsi ike, ngwa anya nnyefe Njirimara, electric insulating Njirimara, na a dị nnọọ obere ọchịchọ banye mmiri mmiri. Ọ na-eguzogide mmiri, diluted inorganic acids. , ma enwere ike imebi ya site na acids oxidizing siri ike dị ka sulfuric acid gbadoro ụkwụ, ma nwee ike zaa ma gbanwee na ụfọdụ ihe mgbaze organic.)
2. Usoro atụmatụ nke PS:
Ebe na-agbaze nke PS bụ 166 Celsius C, nhazi okpomọkụ bụ 185-215 Celsius C, na okpomọkụ na-agbaze bụ 180 ~ 280 Celsius.Maka ihe na-egbochi ire ọkụ, oke dị elu bụ 250 Celsius C, na ire ere dị ihe dịka 290 Celsius C, ya mere nhazi nhazi ya dị obosara.
The ebu okpomọkụ bụ 40 ~ 50 ℃, injection mgbali: 200 ~ 600bar, injection ọsọ na-atụ aro iji a ngwa ngwa injection ọsọ, na ndị na-agba ọsọ na ọnụ ụzọ ámá nwere ike iji niile ot ụdị ọnụ ụzọ ámá.Ihe PS anaghị adị mkpa ka akpọọ nkụ tupu nhazi ọ gwụla ma echekwara ya nke ọma.Ọ bụrụ na achọrọ ihicha, ọnọdụ ihicha akwadoro bụ 80C maka awa 2 ~ 3.
N'ihi obere okpomọkụ nke PS dị ntakịrị, ụfọdụ ihe ọkpụkpụ nwere ike ịme ngwa ngwa ma sie ike mgbe a na-eme ka ha na-ekpo ọkụ.Ọnụego jụrụ oyi na-adị ngwa karịa nke ngwa ngwa nkịtị, na oge mmeghe ebu nwere ike ịbụ na mbụ.Oge plasticizing na oge oyi dị mkpụmkpụ, a ga-ebelata oge okirikiri ịkpụzi;gloss nke ngwaahịa PS ka mma ka ebu okpomọkụ na-abawanye.
Ngwa 3.Typical: ngwaahịa nkwakọ ngwaahịa (akpa, okpu, karama), ihe eji egwuri egwu, ihe eji egwuri egwu, iko, mma, teepu teepu, windo ifufe na ọtụtụ ngwaahịa ụfụfụ - katọn akwa.Mpempe akwụkwọ nri anụ na anụ ọkụkọ, akwụkwọ mmado karama na ihe mkpuchi PS, nkwakọ ngwaahịa ngwaahịa, ihe ụlọ (ebe a na-egbutu, trays, wdg), eletriki (ihe na-ebugharị, ihe ọkụ ọkụ, ihe nkiri mkpuchi, wdg).
(2).HIPS (polystyrene emezigharịrị)
1. Arụmọrụ HIPS:
HIPS bụ ihe PS emegharịrị.Ọ nwere akụkụ rọba 5-15% na molekul.Ike ya dị ihe dị ka okpukpu anọ dị elu karịa nke PS, na ike mmetụta ya na-eme ka ọ dịkwuo mma (mmetụta dị elu nke polystyrene).Ọ nwere ogo retardant ọkụ na mgbawa mgbawa.akara ule, ogo gloss dị elu, akara ike mmetụta dị oke elu, akara ule agbadoro eriri iko, yana akara ule dị ala na-agbanwe agbanwe.
Ihe ndị ọzọ dị mkpa nke ọkọlọtọ HIPS: ike na-ehulata 13.8-55.1MPa;ike ike 13.8-41.4MPa;elongation na nkwụsịtụ 15-75%;njupụta 1.035-1.04 g / ml;Uru.Edemede HIPS enweghị isi.HIPS nwere obere mmịnye mmiri na enwere ike ịhazi ya na-enweghị tupu ihicha ya.
2. Usoro nhazi nke HIPS:
N'ihi na molekul HIPS nwere 5-15% roba, nke na-emetụta mmiri ya ruo n'ókè ụfọdụ, nrụgide injection na ịkpụzi okpomọkụ kwesịrị ịdị elu.Ọnụọgụgụ ya dị jụụ na-adị nwayọọ karịa nke PS, ya mere a na-achọ nrụgide njide zuru oke, oge ijide oge na oge oyi.Usoro ịkpụzi ga-adị ntakịrị ogologo karịa nke PS, na nhazi okpomọkụ na-adịkarị 190-240 Celsius.
HIPS resins na-eji nwayọọ nwayọọ na-amịkọrọ mmiri, ya mere, a naghị achọ ihicha.Mgbe ụfọdụ, oke mmiri dị n'elu ihe ahụ nwere ike ịbanye, na-emetụta ọdịdị ọdịdị nke ngwaahịa ikpeazụ.Enwere ike wepu oke mmiri site na ihicha na 160°F maka awa 2-3.Enwere nsogbu "ọnụ na-acha ọcha" pụrụ iche na akụkụ HIPS, nke nwere ike imeziwanye site n'ịbawanye okpomọkụ nke ịkpụ na ike ijide, na-ebelata nrụgide na oge, wdg, na ụkpụrụ mmiri dị na ngwaahịa ahụ ga-apụta ìhè karị.
Ebe ngwa ngwa 4.Typical: Ebe isi ngwa bụ nkwakọ ngwaahịa na ihe mkpofu, ngwá ọrụ, ngwa ụlọ, ihe egwuregwu na ihe ntụrụndụ, na ụlọ ọrụ mmepụta ihe.Ọkwa retardant ọkụ (UL V-0 na UL 5-V), polystyrene na-eguzogide mmetụta ka emepụtara ma jiri ya mee ihe na mkpuchi TV, igwe azụmahịa na ngwaahịa eletriki.
Iji gaa n'ihu, ọ bụrụ na ịchọrọ ịmatakwu, biko nweere onwe gị ịkpọtụrụ anyị.Baiyear bụ nnukwu ụlọ ọrụ sara mbara nke na-ejikọta plastik ịkpụzi, ịkpụzi injection na nhazi mpempe akwụkwọ.Ma ọ bụ ị nwere ike ịga n'ihu na-aṅa ntị na ụlọ ọrụ akụkọ nke ebe nrụọrụ weebụ anyị: www.baidasy.com , anyị ga-anọgide na-emelite akụkọ ihe ọmụma metụtara ụlọ ọrụ nhazi nhazi.
