Nyob rau hauv ntim yas, Qhov txawv ntawm Qhuav Composite thiab Solvent-Free Composite yog dab tsi?

Qhuav composite yog hnyav-dawb composite feem ntau pom nyob rau hauv cov txheej txheem ntawm cov khoom ntim hnab yas, ob txoj kev sib xyaw no muaj qhov zoo thiab qhov tsis zoo, hnub no peb yuav sib piv thiab tshuaj xyuas rau koj.

Qhuav compound

Qhuav composite yog ib txoj kev sib xyaw uas cov nplaum yog sib npaug ntawm cov nplaum nplaum los ntawm cov menyuam thauj khoom, ziab hauv qhov cub, thiab tom qab ntawd nias thiab txuas rau cov zaj duab xis sib xyaw ntawm cov khoom sib xyaw. Cov ntawv ntim khoom qhuav qhuav muaj ntau yam kev siv, zoo heev corrosion tsis kam rau tshuaj lom neeg cov xov xwm, thiab feem ntau yog siv rau ntim uas muaj alkali, ntsim, roj thiab lwm yam muaj zog corrosion txheem, thiab kuj yog haum rau tshuaj pleev ib ce tsw, emulsifier thiab lwm yam khoom xyaw, tshwj xeeb tshaj yog qee qhov ntim uas yuav tsum tau ua kom kub kub, uas muaj qhov zoo.

Piv nrog rau lwm cov txheej txheem sib xyaw, cov txheej txheem qhuav compounding muaj cov hauv qab no zoo:

(1) Qhov chaw muaj substrate dav dav, tuaj yeem ua cov yas nrog yas, tuaj yeem ua cov yas nrog ntawv, yas nrog hlau thiab ntaub, tsis-woven npuag, thiab lwm yam, txawm tias tsis muaj yas, ntawv nrog hlau kuj tuaj yeem ua ke;
(2) Qhov ceev ntawm cov khoom sib xyaw yog qhov siab, lub zog tev tawm ntawm cov khaubncaws sab nraud povtseg tuaj yeem ncav cuag 1000g / 25mm dav lossis ntau dua, thiab cov khoom ntim qib siab tuaj yeem tsim tau, xws li cov hnab ntim khoom kub kub;
(3) Lub thickness ntawm txhua txheej tuaj yeem xaiv tau ywj pheej thiab tswj kom raug;
(4) tuaj yeem luam tawm ntawm qhov chaw, tuaj yeem luam tawm ntawm qhov thim rov qab;
(5) Kev ceev ceev ntau lawm, kev khiav hauj lwm ceev yog 150-180㎡/0, thiab qhov ceev tshaj tuaj yeem ncav cuag ntau tshaj 200m / g.

Qhov tsis zoo ntawm kev sib xyaw qhuav yog:

(1) Kev sib xyaw yuav tsum tau siv cov nplaum nplaum, muaj cov teeb meem toxicity residual, yog li ntawd, kev ntim khoom ntim qhuav, tshwj xeeb tshaj yog siv ob lub ntsiab lus polyurethane nplaum curing qhuav composite ntim tsis tuaj yeem siv hauv North American thiab European kev lag luam, tab sis tuaj yeem siv tau. tsuas yog muag hauv Southeast Asia, Africa thiab lwm qhov chaw. Tuam Tshoj thiab Nyiv, raws li lub teb chaws cov qauv ntawm cov khoom qhuav tuaj yeem siv rau cov khoom noj thiab tshuaj ntim khoom, cov qauv kev noj qab haus huv yog tag nrho cov khoom xyaw tshuaj lom uas seem tsawg dua lossis sib npaug li 15mg / ㎡:
(2) Vim yog siv ntau cov kua nplaum nplaum ua cov nplaum sib xyaw, vim yog ib puag ncig muaj kuab paug ntawm cov kuab tshuaj tsis muaj zog thiab cov teeb meem tawg thiab tawg:
(3) Cov yeeb yaj kiab qhuav vim yog cov kua nplaum ntau thiab cov nqi siab, tus nqi kuj tseem kim.

Solventless recombination

Qhov sib txawv ntawm cov kuab tshuaj tsis muaj cov khoom ntim zaj duab xis thiab cov khoom sib xyaw qhuav yog cov kuab tshuaj organic tsis yog siv, uas tsis tsuas yog zam cov pa phem los ntawm kev hloov pauv ntawm cov kuab tshuaj organic rau ib puag ncig, tab sis kuj tsis tas yuav tsum tau ua haujlwm ntawm cov kuab tshuaj volatilization thiab ziab. , ncaj qha txo cov nqi tsim khoom, thiab tshem tawm qhov cuam tshuam ntawm cov khoom sib xyaw substrate yooj yim rau cov kuab tshuaj thiab kub kub kom qhuav kev puas tsuaj, kom qhov seem stability ntawm lub ntim zaj duab xis zoo dua.

Solvent-free composite muaj qhov zoo hauv qab no:

(1) Kev tiv thaiv ib puag ncig. Vim tias cov nplaum nplaum tsis muaj cov kuab tshuaj, nws yuav tsis ua rau muaj kuab paug rau ib puag ncig vim muaj kuab paug emissions. Tsis tas li ntawd, cov khoom siv hnyav hnyav tsis muaj suab nrov ntau dua li cov khoom siv hnyav vim nws cov qauv compact thiab txo cov chav kom qhuav. Raws li kev ntsuas tiag tiag, lub suab nrov ntawm cov khoom siv tsis muaj kuab tshuaj sib xyaw feem ntau yog nyob nruab nrab ntawm 70-75Db, thiab hom hnyav raws li feem ntau yog nyob nruab nrab ntawm 85-100Db.

(2) Tus nqi qis. Nyob rau hauv cov nqe lus ntawm cov cuab yeej peev nqi, vim lub compact hnyav-free composite cov cuab yeej, lub hneev taw yog ho me dua li ntawm cov khoom hnyav-raws li cov khoom sib xyaw, thiab tus nqi ntawm cov cuab yeej yog qis dua li cov khoom siv hnyav, thiab muaj. yog tsis xav tau rau hnyav warehouse. Hais txog tus nqi hluav taws xob, lub cev muaj zog ntawm cov khoom siv tsis muaj kuab lom kuj tseem yog kaum ntawm kilowatts tsawg dua li cov khoom siv hnyav.

(3) Kev noj qab haus huv thiab kev nyab xeeb. Cov kuab tshuaj tsis muaj tshuaj tiv thaiv kom tsis txhob muaj cov kuab paug tawm ntawm cov ntsiab lus lossis ua rau muaj ntxhiab tsw, ua rau cov khoom ntim khoom noj muaj kev nyab xeeb thiab muaj kev nyab xeeb dua, thiab kev ua haujlwm muaj kev nyab xeeb, vim tias tsis muaj kev pheej hmoo ntawm hluav taws kub thiab tawg vim yog siv cov kuab tshuaj, tsis muaj pov thawj tawg. yuav tsum ntsuas.

(4) Cov khoom zoo. Vim tias qhov ntsuas kub ua haujlwm qis dua li cov kuab tshuaj, cov yeeb yaj kiab yuav tsis deformed ntawm qhov kub thiab txias. Tam sim no, cov substrate ntawm cov yeeb yaj kiab zoo tib yam tuaj yeem tsim los ntawm cov kua nplaum tsis muaj kuab lom, thiab txawm tias cov yeeb yaj kiab sib xyaw uas tuaj yeem tiv taus qhov kub kub ua noj ntawm 121 degree tuaj yeem tsim los ntawm txoj kev no.

Disadvantages ntawm cov kuab tshuaj-dawb composite:

Tag nrho cov system yuav tsum tau rhuab thiab lub coater yuav tsum tau insulated thaum lub nplaum yog coated. Daim ntawv thov lub sij hawm ntawm cov nplaum sib tov yog luv, thiab lub sij hawm siv zoo tsis ntau tshaj 30min; Cov khoom ntim hnyav, siab nruab nrab tsis kam thiab ultra-siab kub sterilization yog qhov nyuaj rau ua tau raws li qhov yuav tsum tau ua; Tsawg pib viscosity, ntev curing lub sij hawm; Cov txheej txheem siab yog yuav tsum tau.

Ob txoj kev ntawm cov khoom ntim zaj duab xis muaj lawv tus kheej qhov zoo, nyob rau hauv kev xaiv ntawm cov txheej txheem sib xyaw, peb yuav tsum xub xa mus rau qhov xwm txheej ntawm cov khoom ntim, qhov hnyav thiab lwm yam, yog tias lawv tsis tuaj yeem txiav txim siab, koj tuaj yeem sab laj txog kev ntim khoom ntau dua. hnab manufacturers.
