Tawm tsam keeb kwm yav dhau los ntawm kev lag luam ntim cov qauv ntawm lub teeb yuag, tus nqi qis, thiab kev ua haujlwm sib txawv, siab - cuam tshuam polystyrene (HIPS), nrog nws cov khoom sib xyaw tshwj xeeb, tau dhau los ua cov khoom nyiam rau cov zaub mov pallets, ntim hluav taws xob, thiab cov thawv ntim khoom pov tseg. Nws qhov zoo tsis yog tsuas yog xav txog qhov sib npaug ntawm cov cuab yeej cuab tam, tab sis kuj nyob rau hauv nws txoj kev yooj yim ntawm kev ua thiab kev hloov pauv ntawm qhov chaw, muab cov khoom txhawb nqa rau kev tsim khoom thiab kev txhim kho zoo ntawm cov khoom ntim.
Qhov tseem ceeb ntawm kev ua tau zoo ntawm HIPS stems los ntawm nws cov qauv siv ntau theem. Nrog polystyrene raws li cov theem tas mus li thiab butadiene roj hmab microparticles raws li lub sijhawm tawg, cov khoom tuav lub hauv paus rigidity ntawm PS (tensile lub zog 15-}}30 MPa) thiab nto gloss, thaum ua rau muaj kev cuam tshuam lub zog mus rau 6-12 kJ / m², ob peb zaug siab dua li lub hom phiaj PS. Qhov no daws tau qhov teeb meem ntawm nkig ntim tau yooj yim puas thaum lub sij hawm thauj mus los thiab stacking. Qhov sib npaug ntawm rigidity thiab toughness no tso cai rau HIPS pallets tiv taus qee qhov kev sib tw siab thaum tiv thaiv kev sib tsoo thaum lub sij hawm thauj khoom thiab tshem tawm, txo cov nqi thauj khoom.
Nyob rau hauv cov nqe lus ntawm kev hloov kho, HIPS nthuav tawm zoo heev yaj flowability, dav melting ntau (170-220 degree), thiab qis thiab ruaj khov shrinkage (0.4%-0.7%), ua rau nws tshwj xeeb tshaj yog haum rau siab - ceev txhaj molding thiab extrusion. Nyias-walled khoom feem ntau pom nyob rau hauv kev lag luam ntim khoom (xws li cov thawv ntim khoom noj su) tuaj yeem ua tiav cov khoom ntim ntau dhau los ntawm cov txheej txheem prototyping sai, nrog rau qhov siab qhov tseeb, huv npoo tsis muaj burrs, thiab txhim kho ntim sealing thiab zoo nkauj. Nws tus nqi cua txias sai ntxiv ua rau lub voj voog molding, ua tau raws li qhov yuav tsum tau ua ntawm cov khoom loj hauv kev lag luam ntim.
Kev kho deg kev ua tau zoo yog qhov tseem ceeb rau kev nthuav dav cov kev pabcuam ntim cov haujlwm ntawm HIPS. Nws lub zog nruab nrab ntawm lub zog ua kom lub tshuab nqus tsev metallization, cov qauv luam ntawv, lossis cov yeeb yaj kiab sib xyaw, ua tau raws li qhov yuav tsum tau muaj ntawm kev ntim khoom noj (xws li kev tiv thaiv ya raws thiab thaiv lub teeb) thiab kev qhia meej meej. Piv txwv li, cov ntaub ntawv ntim khoom sib xyaw siv HIPS substrates, los ntawm txheej metallization, tuaj yeem txo cov pa oxygen permeability tsawg dua 1/10 ntawm cov yeeb yaj kiab PS zoo tib yam, ua rau lub neej ntev ntawm cov khoom noj khoom haus. Tsis tas li ntawd, HIPS tiv taus cov zaub mov- qib inks thiab adhesives, ua raws li GB 4806 series cov qauv kev nyab xeeb zaub mov, ua kom muaj kev nyab xeeb ntawm cov khoom ntim ncaj qha -.
Kev tiv thaiv ib puag ncig thiab tus nqi-kev ua tau zoo kuj yog HIPS qhov zoo sib tw. Cov ntaub ntawv pov thawj zoo tiv thaiv dej, roj, thiab tsis muaj zog acid / alkali media, ua rau nws haum rau ntau hom ntim xws li cov khoom tshiab thiab cov khoom ci. Thaum tsis hloov kho HIPS muaj qhov txwv huab cua tiv thaiv, qhov sib ntxiv ntawm lub teeb stabilizers tuaj yeem ua tau raws li luv luv - lub sij hawm sab nraum zoov cov kev xav tau (xws li lub khw muag khoom noj khoom haus). Nyob rau hauv cov nqe lus ntawm tus nqi, HIPS raw khoom tus nqi qis dua feem ntau engineering plastics, thiab molding zog noj yog tsawg, uas ua rau ib tug tseem ceeb tag nrho cov nqi tsim tau zoo dua, ua rau nws tshwj xeeb tshaj yog haum rau tus nqi - rhiab heev rau cov neeg siv khoom lag luam.
Tam sim no, HIPS daim ntawv thov hauv kev ntim khoom yog txuas mus rau kev ua haujlwm. Los ntawm cov nplaim taws- kev hloov kho retardant, nws tuaj yeem ua rau hauv ob sab phlu rau cov khoom siv hluav taws xob ntim khoom, ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb hluav taws thaum lub sijhawm thauj mus los; blending nws nrog bio-raws li biodegradable cov ntaub ntawv tuaj yeem tsim cov ntim khoom zoo ib puag ncig, teb rau "kev txwv yas" txoj cai. Cov kev tsim kho tshiab no nthuav dav qhov chaw lag luam rau HIPS.
Raws li tus neeg sawv cev ntawm tus nqi siab -kev ua tau zoo hauv cov khoom ntim khoom, HIPS, nrog rau nws cov kev ua tau zoo ntawm kev sib npaug rigidity thiab toughness, high processing efficiency, deg plasticity, and economic practicality, continues to provide solutions for quality upgrading and cost control in the packing industry. Nws daim ntawv thov qhov tob thiab dav yuav txuas ntxiv nrog kev nce qib hauv cov khoom siv hloov kho tshuab.
