Cov nplaum rau extruded polystyrene ua npuas ncauj raug xaiv rau hom kev ua haujlwm tshwj xeeb, uas yuav tsum tau ua kom zoo, nws hom thiab huab cua huab cua thaum ua haujlwm thiab thaum lub sijhawm ua haujlwm.
Rau sab nraud thiab sab hauv tej hauj lwm, txawv kua nplaum muaj pes tsawg leeg siv. Ib qho ntxiv, cov nplaum rau kev nthuav dav polystyrene yuav tsum muaj qhov tsis muaj roj colyurethane rwb thaiv tsev, tab sis kuj yog txhawm rau txhim kho cov pa thermal ntawm tag nrho lub tsev.
Kua nplaum ntau yam
Yuav ua li cas kua nplaum extruded polystyrene ua npuas ncauj kom ua cov dej khov zoo no, nws tuaj yeem nkag siab los ntawm kev txiav txim siab los ntawm kev txiav txim siab ntawm cov tsiaj ntawm cov khoom sib xyaw ua ke.
Thov xaiv cov kua nplaum uas xav tau yog tsis yooj yim heev. Tag nrho cov nplaum muaj cov khoom sib xyaw muaj ob peb ntu.
Txhua hom kua nplaum tau zoo glued panels.
Nyob ntawm qhov no, lawv tau muab faib ua peb hom loj:
- Bitumen-based kua nplaum;
- polymer MAAs nplaum;
- Polyurethane ua npuas ncauj nplaum.
Tag nrho cov hom no muaj qhov tsim nyog rau gluting extruded extruded extruded shoamred foam, thiab muab cov nplaum ceev thiab txhim khu kev qha cov nplaum ntawm cov chaw glufaces.
Cov khoom xyaw rau cov kua nplaum rau polystyrene ua npuas ncauj yuav tsum tsis txhob suav nrog cov tshuaj acetone thiab roj av, vim tias lawv tsis suav nrog cov kuab tshuaj firvents, cov roj tseem ceeb lossis zoo sib xws tshuaj.
Bitumen
Bituminous kua nplaum tsis tas yuav ua ntej thov
Cov kua nplaum bituminous yog cov plaster-nplaum sib tov, nyob rau hauv uas bitumen yog siv ua phau ntawv. Nws yog txig ua ke nrog nthuav dav polystyrene thiab fastens nws zoo nrog ib qho kev them rau saum npoo. Bituminous kua nplaum yas thiab tsis tas yuav tsum preheating ua ntej siv.
Vim yog cov ntsiab lus ntawm cov kua nplaum ntawm babumen, qhov chaw uas tau muab cov kua nplaum pleev rau saum npoo ntawm cov khoom, muaj cov dej tsis muaj dej siab.
Tshooj ntawm cov ncauj lus: ntau yam ntawm cov phuam qhwv caj dab
Qhov no tso cai rau kev siv cov tshuab no thaum rwb thaiv tsev nrog cov khoom siv polyurethan, thaum ua npuas dej ntawm cov av polystyrene ua npuas ncauj yuav siv cov qauv raws li ya raws.
Rau cov khoom nplaum zoo ntawm cov chaw glued, nws yog ib qho tsim nyog los them sai sai rau daim ntawv thov ntawm cov nplaum muaj pes tsawg ntawm cov khoom. Nws tau faib rau ib txheej me me uas nrog lub zuag xab taws.
Qhov no yuav ua rau nws tsis tau txuas rau cov ntaub ntawv siv khov kho, tab sis kuj yuav ua kom muaj kev tsim cov khoom siv dej tsis zoo ntawm lawv. Tom qab ntawd, koj yuav tsum tsim ib qho siab ntawm cov ntaub ntawv hais saum toj no rau ib nrab ib teev. Qhov no tuaj yeem ua tau siv cov spacers, clamps lossis siv lwm txoj hauv kev muaj.
Npaj cov kua nplaum ntawm lub sijhawm me me tsis tas yuav siv ntau dua thiab nqa tawm hauv feeb nrog kev pab ntawm cov nyiaj uas tsim nyog rau cov haujlwm zoo.
Polymer Maas lo
Cov kua nplaum no tau siv rau hauv cov rwb thaiv tsev ntawm cov pob zeb ua.
Cov nplaum no yog tsim los nrog cov chaw ua haujlwm ua los ntawm cov pob zeb ua los ntawm cov pob zeb ua kom huv, cib, ua pob zeb ua, hypina thiab ntoo. Nws tuaj yeem siv thaum ua yeeb yam sab hauv thiab facade ua haujlwm. Cov mixtures muaj cov Portland Maas thiab ntau yam khoom siv uas muab cov yas ua kom yooj yim thiab lwm yam khoom rau cov khoom lag luam nplaum.
Ua ntej thov, tob siab zoo impregnation ntawm cov chaw ntawm cov ntaub ntawv glued yog qhov yuav tsum tau ua. Tom qab soaring, polymer Maas Adhesives tsim cov khoom ruaj khov.
Polymer MAAs nplaum yog siv yog tias tsim nyog thov thiab tom ntej ua tiav tiav ntawm cov npoo kho.
Vim tias cov khoom lag luam siab, nws yog dav siv rau cov ntawv nplaum ntawm polystyrene ua npuas ncauj ntawm cov chaw qab nthab, ua rau muaj kev tsim txiaj thiab txhim khu kev qha zoo thiab txhim khu kev qha zoo thiab txhim khu kev qha zoo thiab txhim khu kev qha cov khoom siv qab nthab thiab txhim khu kev qha.
Polyurethane Ua npuas ncauj lo
Cov nplaum no tau muab rau 10 feeb.
Polyurethane ua npuas ncauj yog ib txhais tau tias zoo heev thiab txhim khu kev qha txhais tau tias yog gluing extruded supruded polystyrene ua npuas ncauj rau ntau qhov chaw. Teeb tsa tom qab ua ntawv thov rau saum npoo ntawm cov khoom tsis muaj ntau tshaj 10 feeb.
Tshooj nyob rau lub ncauj lus: Hmo ntuj kav dej - 2019: Mixers, Sinks thiab Chaw Tso Khoom thiab Chaw Tso Khoom ntawm Amazing Tsim
Txhawm rau kom ua npuas dej polystyrene ua npuas ncauj nyob rau saum npoo ntawm 10 m 1, ib qho kev noj npuas dej ntawm cov khoom nplaum ntawm 20 txog 25 kg, nyob ntawm seb cov sib tov sib xyaw thiab qhov zoo ntawm cov chaw glued. Kom paub cov ntsiab lus ntawm yuav ua li cas thiab yuav ua li cas rau cov npaus, saib daim video no:
Kev siv polyurethane ua npuas ncauj kua nplaum muaj cov ntsiab lus zoo hauv qab no:
- kev siv nyiaj txiag;
- Thaum siv tsis emit cov tshuaj phem;
- dries tom qab 2-3 teev;
- tsis tas yuav muaj kev npaj ua si ntxiv;
Polyurethane ua npuas ncauj muaj pes tsawg leeg muaj tus nqi siab
Nrog kev pab ntawm kev ua npuas ncauj, saum npoo ntawm cov npoo ntawm cov chaw los ntawm extruded nthuav dav polystyrene tau ua nrawm thiab yooj yim. Qhov tsis zoo ntawm hom no yog tus nqi siab ntawm polyurethane ua npuas ncauj nplaum.
Cov kev cai tswj hwm thiab muaj peev xwm ntawm cov ntim thiab ntim hauv cov kua nplaum rau ua npuas dej thiab nthuav polystyrene tuaj yeem xaiv raws li cov ntaub ntawv teev nyob rau hauv lub rooj:
| Lub npe ntawm cov kua nplaum | Lub peev xwm | Kev tau txais ib 1M2. |
|---|---|---|
| Paj me ntsis kua nplaum | Los ntawm 1 mus rau 50 litres | Los ntawm 1 txog 1.5 kg |
| Polymer xis mas | Hnab 20-25 kg | Los ntawm 4 txog 5 kg |
| YEES-NPUAS | KHEEJ KHEEJ 75-100 ml | 100 ml |
Kev siv cov npe ntawm cov nplaum sib txuas thiab kev ua raws li cov thev naus laus zis thiab ua npuas dej ua kom tau cov txheej txheem ua haujlwm yooj yim, nrawm thiab muaj txiaj ntsig.
