Cov yooj yog lub peev xwm ntawm cov khoom siv los hloov nws cov duab los ntawm khoov yam tsis tawg. Kev yoog raws yog lub peev xwm ua kom yoog raws, hloov pauv mus rau qhov hloov pauv hauv lub cev thiab kev txav mus los. Nws yog cov neeg kho tshuab yooj.
Txawm li cas los xij, nws yog ib qho tseem ceeb kom tsis txhob cuam tshuam qhov hloov pauv tau - nruj nruj (hloov pauv) nrog qhov muag muag - tawv tawv (tawv tawv). Cov khoom siv mos tuaj yeem ua pwm thiab hloov pauv ntau txoj hauv kev thiab tsis yog los ntawm kev khoov (nws qhov ua tsis tiav yog ua tiav). Cov khoom siv hloov pauv tsis tuaj yeem ua pwm thiab tsuas lees txais kev hloov pauv thaum khoov.
Cov khoom siv tawv yuav tsis nyuaj. Piv txwv li, ntoo yog cov khoom siv tawv tab sis muaj qhov tawv tawv, vim tias lub zog me me yuav tsum tau txhawm rau nws, piv rau, piv txwv li, hlau.
Cov piv txwv muab ntawm cov ntaub ntawv hloov pauv tau thiab nruj yog ib txwm txheeb ze. Piv txwv li, cov duab los qhia yog ib yam ntawm cov khoom siv tawv uas tsis zoo li ntawv, cov khoom siv ua los ntawm tib cov ntaub, uas tseem yog qhov hloov pauv tau ntau dua. Tab sis cov duab los kuj muaj qhov hloov pauv me ntsis piv rau, piv txwv li, hlau.
Ntawm qhov tod tes, muaj cov ntaub ntawv uas tuaj yeem hloov tau lossis nruj raws li lawv cov tuab. Piv txwv li, polyethylene ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom mus rau hauv txheej HDPE (HDPE) tuaj yeem hloov pauv tau yooj yim, tab sis nws yog cov tawv ntau dua hauv cov txheej tuab, thiab nws yog cov khoom siv los ntawm cov khoom uas muaj xws li cov thoob khib nyiab lossis cov kav dej loj. Ntau yam ntawm cov ntaub ntawv uas tau piav qhia hauv qab no tuaj yeem hloov pauv tau thiab nruj.
- Saib kuj: Cov khoom siv ywj
Piv txwv ntawm cov ntaub ntawv hloov pauv
- Ntawv. Nws yog ib daim ntawv nyias nyias ntawm cov nplej zom uas tau ua los ntawm cov zaub hauv av. Daim ntawv hloov pauv tau ntau dua yog tias nws muaj kev kho kom zoo, uas yog, nws cov fibers tsis muaj dej ntau. Cov ntaub ntawv nrog cov dej uas muaj dej muaj zog dua.
- LDPE / LDPE (Tsawg ntom Polyethylene). Nws yog ib hom thermoplastic rov ua dua tshiab uas tau siv rau hauv cov ntim tau hloov pauv, xws li hnab, cov yeeb yaj kiab ua tus kheej thiab hnab looj tes. Txawm hais tias nws kuj tseem siv rau hauv qhov nruj ntawm cov ntim (xws li lub raj mis lub hau), nws tsuas yog siv hauv cov ntawv nyias nyias uas ua rau nws yoog raws. Nws yog siv rau nws cov tshuaj tiv thaiv zoo. Nws tseem tuaj yeem tiv taus qhov kub txog 80ºC, lossis 95ºC rau lub sijhawm luv. Vim nws txoj kev yoog raws, nws muaj kev tiv taus siab rau kev cuam tshuam cov tshuab.
- Txhuas Nws yog cov hlau tsis tsuas yog hloov pauv tab sis kuj muag muag, uas yog, nws tsis yooj yim heev. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias hauv cov txheej tuab nws ua tawv. Vim li no, txhuas tuaj yeem siv tau rau ntim tau yooj yim (txawm tias yog hu ua "aluminium ntawv ci") tab sis kuj tseem nyob hauv cov txheej txheem nruj ntawm txhua qhov ntau thiab tsawg, los ntawm cov kaus poom zaub mov mus rau dav hlau.
- Silicone. Nws yog inorganic polymer. Vim nws ruaj khov ntawm qhov kub thiab txias, nws tau siv dav los ua cov pwm thiab cov nplaum hauv kev lag luam. Nws kuj tseem siv tau ua kom tsis muaj menyuam nyob rau hauv kev cog qoob loo, xws li cog lub mis, lub hauv paus prostheses thiab lub plawv.
- Nws tuaj yeem pab koj: Cov ntaub ntawv zas hlau
Piv txwv ntawm cov khoom siv tawv
- Ntawv los xij. Nws tau tsim los ntawm ntau txheej txheej ntawm cov khoom siv hloov pauv tau: ntawv. Txawm li cas los xij, cov duab los qhia tau nruj vim nws cov tuab thiab tseem yog vim cov txheej txheem uas cov fibers hla mus: gluing. Nws tuaj yeem tsim los ntawm cov khoom siv rov ua dua tshiab, uas ua rau nws yog cov khoom pheej yig. Vim nws txoj kev nruj thiab tus nqi qis, nws yog cov khoom siv feem ntau xaiv los ua cov thawv uas tso cai thauj lwm yam khoom uas tsis yooj yim dua.
- PET (polyethylene terephthalate). Nws yog cov yas uas muaj kev nruj heev, tab sis kuj muaj qhov nyuaj thiab tiv taus. Nws tau siv hauv cov dej haus, kua txiv thiab ntim tshuaj vim nws tiv taus cov tshuaj lom neeg thiab huab cua (cua sov, av noo).
- Polypropylene (PP). Nws yog ib yam ntawm cov ntaub ntawv uas tuaj yeem txiav txim siab nruj lossis yoog raws nws qhov tuab. Txawm li cas los xij, nws feem ntau yog siv rau cov khoom tawv. Nws yog qhov nruab nrab nruab nrab ntawm cov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom mus rau nruab nrab ntawm polyethylene ntom ntom ntom ntom ntom ntom ntom. Nws tiv taus qhov kub thiab txias rau feem ntau cov kua qaub thiab alkalis. Lawv tau siv hauv kev tsim cov ntaub ntawv CD, rooj tog zaum, tais thiab txiav cov laug cam. Nws yog cov khoom siv dav siv hauv kev ua zaub mov noj thiab tshuaj (los ntawm cov rooj tog zaum hauv chav ua haujlwm rau kev kho qhov muag) vim nws tsis tawm ib yam dab tsi uas seem lossis muaj tshuaj lom paug. Nws yog cov khoom siv xaiv rau kev tso tshuaj lom neeg vim nws tsis kam rau lawv. Hauv nws daim ntawv hloov pauv nws tau siv rau hauv cov ntaub qhwv, hlua thiab xov, tab sis kuj tseem hauv cov yeeb yaj kiab nyias siv hauv ntim khoom noj.
- Iav Nws yog cov khoom siv inorganic tam sim no hauv qhov. Nws yog nruj thiab muaj lub siab tawv, uas yog hais tias, nws muaj ntau yam tsis kam rau puas, txiav, khawb thiab nkag mus. Dua li qhov no, iav cov khoom ntawm txhua daim duab tuaj yeem tsim tau vim tias nws tuaj yeem ua pwm ntawm qhov kub siab tshaj 1,200 ºC. Thaum qhov kub tau poob qis dua, nws dhau los ua nruj dua hauv qhov tshiab tau txais.
- Hlau. Nws yog cov hlau tawv, muaj qhov ua tau zoo thiab ntom ntom. Nws yog cov hlau tawv siv los ntawm tus txiv neej, ntxiv rau ua ib qho ntawm cov khoom siv ntau tshaj plaws hauv ntiaj teb cov av. Nws yog siv los tsim cov hlau, lwm cov hlau tawv, uas yog cov hlau (sib xyaw) ntawm cov hlau thiab carbon.
- Ntoo. Nws yog cov ntsiab lus tseem ceeb ntawm cov ntoo ntoo thiab ib txwm ua kom nruj. Cov "ntoo" hloov pauv tau ntawm cov nroj tsuag raug hu ua qia thiab tsis muaj ntoo. Ntoo tau siv los tsim cov khoom nruj xws li cov khoom zoo nkauj, cov tais diav, tsev, lossis nkoj. Tsis zoo li lwm yam khoom siv tawv xws li iav lossis hlau, uas tuaj yeem yaj kom siv cov duab tshiab, ntoo raug txiav, txiav los yog muab xuab zeb, uas yog hais tias nyob rau hauv tsis muaj cov ntaub ntawv nws tsis ua cov khoom siv tawv.
