Cov lus nug feem ntau uas cov neeg feem coob nug txog cov tshuaj siv hauv kev tsim kho yog dab tsi. Polymer, uas yog ib yam khoom siv hauv kev tsim kho, kuj suav nrog hauv cov khoom siv hauv lub neej txhua hnub. Polymer, uas muaj ob hom sib txawv xws li ntuj thiab hluavtaws, txawm tias pom muaj nyob hauv peb cov DNA.

Raws liBaumerk, tus kws tshaj lij tshuaj siv hauv kev tsim kho, peb yuav teb cov lus nug txog dab tsi yog polymer hauv peb tsab xov xwm, thaum piav qhia txog nws cov cheeb tsam siv thiab lawv siv li cas. Tom qab nyeem peb tsab xov xwm, koj yuav nkag siab tias cov polymer, uas pom muaj nyob rau hauv ntau cov ntaub ntawv siv hauv cov haujlwm tsim kho, pab txhawb rau cov qauv.

Yog xav paub ntxiv txog mastic, lwm yam khoom siv hauv tsev uas siv ntau zaus, koj tuaj yeem nyeem peb tsab xov xwm hu uaMastic yog dab tsi? Mastic siv qhov twg?

Polymer yog dab tsi?

Cov lus teb rau lo lus nug txog lub ntsiab lus ntawm polymer yog dab tsi tuaj yeem muab los ntawm kev sib xyaw ua ke ntawm cov lus Latin "poly" txhais tau tias ntau thiab "mer" txhais tau tias rov ua dua. Polymer feem ntau siv ua ke nrog yas lossis resin hauv kev lag luam tshuaj siv hauv kev tsim kho. Qhov tseeb, cov polymer suav nrog ntau yam khoom siv nrog ntau yam khoom. Lawv pom muaj nyob rau hauv ntau yam khoom siv hauv tsev siv hauv lub neej txhua hnub, khaub ncaws, khoom ua si, thiab qhov tseem ceeb tshaj plaws hauv cov ntaub ntawv tsim kho siv rau kev rwb thaiv tsev.

Ib qho polymer yog ib qho tshuaj lom neeg uas cov molecule txuas ua ke ua cov saw ntev, rov ua dua. Vim lawv cov qauv, polymers muaj cov yam ntxwv tshwj xeeb uas tuaj yeem hloov kho rau ntau yam kev siv. Polymers raug muab faib ua ob hom: ntuj thiab hluavtaws. Roj hmab, piv txwv li, yog cov khoom siv polymeric ntuj uas tau siv rau ntau txhiab xyoo. Nws muaj cov yam ntxwv zoo heev elasticity vim yog cov saw polymer molecular tsim los ntawm xwm.

Cov polymer ntuj uas muaj ntau tshaj plaws hauv ntiaj teb yog cellulose, ib qho organic compound pom nyob rau hauv cov phab ntsa cell ntawm cov nroj tsuag. Cellulose feem ntau siv rau hauv kev tsim cov ntaub ntawv xws li cov khoom ntawv thiab textiles. Cov polymers ua los ntawm tib neeg lossis cov khoom siv hluavtaws suav nrog cov ntaub ntawv xws lipolyethylenethiab polystyrene, cov yas uas pom ntau tshaj plaws hauv ntiaj teb, pom muaj nyob rau hauv feem ntau cov khoom. Qee cov polymers tsim tau yooj ywm, thaum lwm cov muaj cov qauv ruaj khov tas mus li.

Cov yam ntxwv ntawm cov polymers yog dab tsi?

Qhov ua haujlwm ntawm cov ntaub ntawv uas ua rau kom muaj zog hauv cov haujlwm tsim kho yog qhov tseem ceeb heev. Cov khoom siv ntawm cov tshuaj lom neeg uas ua rau lub neej ntawm cov tsev ntev dua thiab ua rau qhov chaw nyob xis nyob kuj yuav tsum nyob rau theem txaus. Yog li ntawd, cov ntaub ntawv polymer sawv tawm nrog ntau yam khoom sib txawv. Cov polymers uas tuaj yeem tsim tawm hauv ib puag ncig tshuaj lom neeg tuaj yeem muaj cov khoom xav tau nyob ntawm thaj chaw siv.

Ua tsaug rau cov yam ntxwv no, cov polymers ua rau tiv taus cov kev cuam tshuam hnyav uas tuaj yeem ntsib thaum siv thiab dhau los ua cov kev xaiv tsim nyog tshaj plaws rau kev tsim cov tshuaj siv hauv kev tsim kho. Yog li ntawd, cov ntaub ntawv tsim kho uas ua los ntawm polymer uas tiv taus dej thiab tshuaj lom neeg yog qhov nrov heev.

Cov Hom Polymers yog dab tsi?

Ntxiv rau cov lus nug txog dab tsi yog polymer thiab nws cov khoom yog dab tsi, lwm qhov teeb meem tseem ceeb uas yuav tsum tau teb yog cov hom polymers muaj nyob hauv khw. Polymers raug muab faib ua 2 pawg tseem ceeb: thermoplastics, thiab thermosets. Qhov tseem ceeb tshaj plaws uas ua rau qhov sib txawv ntawm cov hom polymer no yog lawv cov tshuaj tiv thaiv thaum lawv ntsib cua sov.

1. Cov Khoom Siv Thermoplastic

Cov thermoplastics yog cov resin uas khov kho thaum sov tab sis ua yas thiab mos thaum raug cua sov. Tom qab ua tiav, feem ntau los ntawm kev txhaj tshuaj molding lossis tshuab molding, thermoplastics coj cov duab ntawm cov pwm uas lawv tau nchuav ua ib qho yaj thiab khov kho rau hauv cov duab xav tau los ntawm kev txias. Qhov tseem ceeb ntawm thermoplastics yog tias lawv tuaj yeem thim rov qab, rov ua kom sov, rov yaj, thiab rov ua dua tshiab.

Txawm hais tias cov thermoplastic polymers muab cov txiaj ntsig xws li lub zog cuam tshuam siab, kev ywj pheej, kev hloov pauv, thiab kev tiv taus cov tshuaj lom neeg, lawv kuj muaj qhov tsis zoo xws li mos thiab yaj ntawm qhov kub qis.

2. Cov khoom siv thermoset

Qhov txawv tseem ceeb ntawm cov thermoset thiab thermoplastic polymers yog lawv cov tshuaj tiv thaiv rau cua sov. Cov thermoplastic polymers mos nrog cua sov thiab hloov mus ua kua. Yog li ntawd, cov txheej txheem kho yog rov ua dua, txhais tau tias lawv tuaj yeem rov ua dua thiab rov ua dua tshiab. Thaum muab tso rau hauv pwm thiab cua sov, cov thermoset khov rau cov duab tshwj xeeb, tab sis cov txheej txheem khov no cuam tshuam nrog kev tsim cov kev sib txuas tshwj xeeb hu ua cross-links, uas tuav cov molecules nyob rau hauv qhov chaw thiab hloov pauv qhov xwm txheej tseem ceeb ntawm cov khoom siv.

Hauv lwm lo lus, cov thermoset polymers muaj cov qauv uas tiv thaiv lawv kom tsis txhob yaj thiab rov pwm thaum kho. Tom qab kho, lawv khaws lawv cov duab hauv qab cua sov thiab tseem khov kho. Cov thermosetting polymers tiv taus kub ntau dua, muaj kev ruaj khov ntawm qhov ntev, thiab tsis tuaj yeem hloov kho lossis ncaj.

Cov Cheeb Tsam Siv Polymer

Muaj ntau yam khoom siv ua los ntawm cov yas thiab cov organic, xws li cov yas, roj hmab, cov nplaum, cov nplaum, cov ua npuas dej, cov xim pleev, thiab cov tshuaj lo, yog ua los ntawm cov polymers. Cov polymers uas siv ntau tshaj plaws hauv kev tsim kho suav nrog cov xim pleev, cov ntaub thaiv dej tsis nkag, cov tshuaj lo, cov tshuaj lo rau ru tsev thiab hauv pem teb, thiab txhua yam khoom siv uas peb xav txog.

Nrog rau kev tsim ntau txhiab hom polymers hauv khw hauv chaw kuaj mob, cov khoom siv rau kev siv tshiab yeej ib txwm tshwm sim. Cov polymers, uas pom muaj nyob rau hauv yuav luag txhua yam khoom siv hauv tsev, muaj txiaj ntsig zoo rau kev tiv thaiv dej. Cov ntaub ntawv rwb thaiv tsev ua los ntawm polymer, uas tuaj yeem siv rau ntau qhov chaw xws li pob zeb ua vaj tse, hlau, txhuas, ntoo, thiab bitumen npog, tseem ua tau zoo txawm tias nyob rau qhov kub qis, thiab muaj kev tiv taus acid thiab base siab, yog cov khoom tseem ceeb ntawm cov haujlwm tsim kho.

Yuav ua li cas siv cov khoom siv rwb thaiv tsev uas ua los ntawm polymer?

Cov ntaub ntawv rwb thaiv tsev uas ua los ntawm polymer muaj ntau hom sib txawv los ntawm Baumerk. Kev siv cov ntaub ntawv uas muab los ua daim npog thiab kua kuj ua txawv.

Qhov tseem ceeb tshaj plaws uas yuav tsum xav txog thaum thovSBS Hloov Kho, Bituminous Waterproofing Membraneyog tias thaj chaw thov yuav tsum tsis muaj hmoov av thiab av qias neeg. Yog tias muaj qhov tsis zoo ntawm qhov chaw, lawv raug kho nrog mortar. Tom qab ntawd, cov polymer based bituminous cover raug muab tso rau ntawm daim membrane primer uas muab tso rau ntawm qhov chaw thiab lo rau ntawm qhov chaw siv lub teeb hluav taws.

Thaum thovHYBRID 120los yogHYBRID 115, qhov chaw raug ntxuav kom huv si thiab cov kab nrib pleb raug du. Tom qab ntawd, cov khoom, uas twb npaj siv lawm, raug siv rau ntawm qhov chaw ua ob txheej siv txhuam, lub log lossis rab phom tsuag.

SUPER TACK 290, lwm yam khoom siv polymer hauv Baumerk cov khoom teev npe, yog siv rau kev sib txuas cov ntaub nplaum dej rau ntawm qhov chaw. Ua tsaug rau nws qhov kev ua tau zoo heev, nws muab tib lub zog rau lub sijhawm ntev hauv cov chaw uas nws tau siv. Ib yam li lwm cov ntaub ntawv, qhov chaw yuav tsum tau ntxuav tag nrho ntawm cov av thiab hmoov av ua ntej siv. Tom qab ntawd SUPER TACK 290 raug siv ntsug thiab kab rov tav ntawm 10-15 cm sib nrug kom cua nkag tau. Thaum kawg, cov khoom siv uas yuav tsum tau lo rau yog muab tso los ntawm kev siv lub zog me me kom cov nplaum tuab tsawg kawg yog 2-3 hli.

Peb tau muab cov lus teb rau lo lus nug ntawm polymer yog dab tsi los ntawm kev ua qhov kev tshuaj xyuas kom ntxaws. Tsis tas li ntawd, peb kuj tau piav qhia txog thaj chaw siv polymer thiab cov khoom siv polymer siv rau kev tiv thaiv dej li cas. Cia peb nco ntsoov koj tias koj tuaj yeem nrhiav tau cov ntaub ntawv tiv thaiv dej polymer thiab ntau lwm yam khoom siv rwb thaiv tsev ntawm Baumerk.tshuaj siv hauv kev tsim khoKoj ua tautiv tauj Baumerkkom tau raws li koj cov kev xav tau hauv koj cov haujlwm tsim kho hauv txoj kev raug tshaj plaws.
