Yog vim li cas vim li cas cov yas npias mugs tuaj yeem hloov cov iav tsoos thiab muaj qhov zoo tshwj xeeb hauv chav noj mov thiab kev lom zem chaw yog los ntawm kev sib koom ua ke ntawm lawv cov khoom siv, molding mechanisms, thiab kev tsim qauv. Kev nkag siab txog cov ntsiab cai no yuav pab kom nkag siab qhov kev ua tau zoo ntawm cov ciam teb thiab muaj feem cuam tshuam thaum xaiv, siv, thiab tshawb fawb thiab txhim kho.
Los ntawm cov ntaub ntawv tshawb fawb, cov matrix ntawm yas npias mugs feem ntau yog ua los ntawm cov zaub mov- qib polymers, xws li polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), thiab biodegradable bio-raws li resins. Cov polymers no muaj ntev - chain entanglement thiab van der Waals rog nyob rau hauv lawv cov qauv molecular, muab lawv lub teeb yuag, yooj, thiab yas. Polypropylene, vim nws qhov siab molecular saw tsis tu ncua thiab nruab nrab crystallinity, ua ke zoo heev cuam tshuam tsis kam thiab kub tsis kam, tswj nws cov tawv thiab tiv thaiv brittleness thaum tuav npias ntawm qhov kub thiab txias. Polystyrene muaj cov pob tshab siab, uas muaj txiaj ntsig zoo rau kev nthuav tawm cov xim thiab ua npuas ncauj txheej ntawm npias, tab sis nws cov kev cuam tshuam tsis zoo kuj tsis muaj zog, thiab nws feem ntau sib xyaw nrog cov tshuaj tawv tawv los txhim kho lub zog. PET muaj cov khoom thaiv zoo heev thiab pob tshab, ua rau nws tsim nyog rau luv luv - lub sijhawm rov siv dua thiab qhov chaw txias txias. Biodegradable bio-raws li resins, polymerized los ntawm cov nroj tsuag- muab cov monomers, tuaj yeem decomposed rau hauv carbon dioxide thiab dej los ntawm cov kab mob nyob rau hauv tej yam kev mob, muab cov khoom hauv paus rau kev tiv thaiv ib puag ncig xav tau.
Lub hauv paus ntsiab lus molding txiav txim siab qhov kev ua haujlwm zoo thiab kev ua haujlwm ntawm lub khob. Cov txheej txheem tseem ceeb yog kev txhaj tshuaj molding, qhov twg cov yas granular yog rhuab mus rau lub xeev molten thiab txhaj rau hauv cov pwm pwm kab noj hniav nyob rau hauv siab. Tom qab tuav lub siab thiab txias, cov khoom tiav yog demolded. Cov txheej txheem no tso siab rau kev tswj xyuas qhov kub thiab txias, siab, thiab txias npaum li cas: qhov kub thiab txias ua kom yaj fluidity, ua kom yooj yim sau cov kab noj hniav; kev kub siab ua kom cov phab ntsa tuab tuab thiab rov ua dua cov pwm kev ntxhib los mos; gradient txias txo qhov kev ntxhov siab sab hauv thiab shrinkage deformation, tiv thaiv cov kab nrib pleb thiab warping. Kub nias thiab lub tshuab nqus tsev tsim feem ntau yog siv rau cov khob tuab lossis tshwj xeeb zoo li lub khob. Los ntawm cua sov thiab softening cov ntaub ntawv thiab tom qab ntawd siv lub siab los yog nqus adsorption, lub zog hauv zos thiab qhov kub thiab txias tuaj yeem txhim kho. Pwm tsim yuav tsum xav txog lub khob lub npoo, cov qauv tsim ntawm lub qia, thiab cov khoom siv sib xyaw ua ke, kom ntseeg tau tias cov khoom tiav yog lub teeb yuag thaum muaj peev xwm txaus-cov kabmob thiab kev cuam tshuam.
Lub hauv paus ntsiab lus ua haujlwm tom qab yas npias mugs nyob hauv lawv qhov kev hloov pauv mus rau qhov chaw siv. The low density and elastic modulus of plastic allow it to absorb impact energy better than glass, dispersing stress through deformation upon impact and reducing the probability of breakage. Tsim nyog cov phab ntsa tuab thiab txhawb nqa cov ribs txhim kho cov load-cov kabmob muaj peev xwm ntawm hauv qab thiab tuav, tiv thaiv deformation los ntawm tuav lossis stacking. Cov tshuaj tiv thaiv - pos huab txheej siv cov qauv hydrophilic los yog ntxeem tau los txo qhov nro ntawm cov kais dej, ua kom pom tseeb. Kev tiv thaiv -slip kev ntxhib los mos nce tuav ruaj khov los ntawm kev nce cov coefficient ntawm kev sib txhuam.
Hais txog qhov ntsuas kub thiab tshuaj lom neeg ruaj khov, cov khoom noj uas tsim nyog- qib plastics tswj kev tsiv teb tsaws thiab leaching theem nyob rau hauv kev nyab xeeb txwv nyob rau hauv lub weakly acidic ib puag ncig ntawm npias thiab nyob rau hauv qis - qhov kub thiab txias, kom huv si haus. Cov ntaub ntawv biodegradable cia siab rau cov enzymes secreted los ntawm cov kab mob ua kom puas cov kab mob polymer, ua tiav cov phooj ywg zoo ib puag ncig.
Hauv kev xaus, lub hauv paus ntsiab lus tom qab yas npias mugs yog qhov tshwm sim ntawm kev sib txuas ntawm cov khoom siv molecular, molding txheej txheem mechanics, thiab kev tsim qauv. Nrog nws lub teeb yuag, cuam tshuam- tiv taus, nyab xeeb, thiab ruaj khov, ua ke nrog ntau hom kev kho mob thiab kev tsim kho ib puag ncig, nws muab cov suab lus tshawb fawb thiab cov tswv yim daws teeb meem rau cov kev pabcuam niaj hnub haus.
