Hauv kev tsim tshuaj lom neeg niaj hnub thiab kev txhim kho cov khoom tu tus kheej, polydimethylsiloxane (PDMS) tau dhau los ua cov khoom siv tsis tseem ceeb vim nws qhov tshwj xeeb physicochemical stability. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev siv siab -viscosity, Jiujiang Deepsea Technology tau qhia nws cov PDMS-5000 cS methyl silicone roj. Vim nws cov tshuaj inertness zoo heev, zoo shear stability, thiab superior thermal stability, cov khoom no tau dhau los ua ib qho kev daws teeb meem rau kev kho tsheb, kev tu tus kheej, thiab kev tsim khoom siv.
I. Core Physicochemical Properties
PDMS-5000 cS yog siab -viscosity linear polydimethylsiloxane polymer. Nws muab kev lag luam-kev ua tau zoo hauv kev tswj viscosity thiab tshuaj purity.
Lub cev tshwm sim:
Lub pob tshab tag nrho, yam tsis muaj xim, tsis muaj ntxhiab, thiab tsis yog - kua tshuaj lom uas qhia tsis muaj ntxhiab tsw lossis xim rau cov khoom tiav.
Thermal stability:
Nrog rau qhov qhib -khob flash point tshaj 321℃thiab tsis tshua muaj volatility, nws tswj kev ua haujlwm ruaj khov txawm tias nyob rau hauv lub sijhawm ntev - qhov kub thiab txias yam tsis muaj kev puas tsuaj loj lossis degradation.
Viscosity -Tsub Coefficient:
Lub viscosity -kub coefficient ntawm 0.61 qhia tau hais tias tsawg viscosity variation nyob rau hauv ib tug dav kub ntau yam, muab ib tug zoo xws li cov neeg kho tshuab damping thiab lubrication kev ua tau zoo.
Nto Zog thiab Nto Tension:
Nws lub zog tsis tshua muaj zog thiab qhov nro tsis tshua muaj kev sib kis tau zoo, lubricity, thiab cov khoom siv hydrophobic.
II. Kev daws teeb meem kev thov
Hauv kev siv cov tswv yim, PDMS-5000 cS yog ntau tshaj li cov tshuaj ntxiv-nws yog ib qho kev daws teeb meem zoo rau kev daws ntau yam kev tsim khoom thiab kev sib tw.
Zoo Shear Stability thiab Damping Performance:
PDMS-5000 cS nthuav tawm tshwj xeeb tsis kam rau cov neeg kho tshuab shear yam tsis muaj qhov tseem ceeb ntawm cov molecular degradation. Hauv kev poob siab, cov khoom siv hydraulic, thiab lwm yam kev siv uas xav tau kev ua haujlwm siab damping, nws muab cov cushioning zoo heev thaum txuas cov cuab yeej siv lub neej.
Enhanced Surface Appearance (Color Enhancement):
Hauv kev kho tsheb polishing thiab rooj tog zaum, qib no ua kom zoo dua qhov ci ntsa iab thaum txhim kho xim qhov tob, rov ua kom cov hnub qub rau qhov nplua nuj, zoo li - tshiab tsos.
Superior Protective Barrier:
Nws lub hauv paus hydrophobicity thiab tshuaj inertness ua rau nws tsim ib zaj duab xis tiv thaiv breathable ntawm cov chaw kho mob. Nyob rau hauv daim tawv nqaij formulations, zaj duab xis no tso cai rau cov tawv nqaij ib txwm transpiration thaum pab tiv thaiv sab nraud ya raws thiab ib puag ncig irritants.
III. Ntau-Sector Applications
Kev Kho Tus Kheej thiab Kev Kho Hniav
PDMS-5000 cS tau dav siv los ua cov khoom tseem ceeb hauv cov tshuaj tiv thaiv, tshuaj pleev, thiab lwm yam kev kho tawv nqaij.
Velvety Skin Feel:
Tsis zoo li qis- viscosity silicone roj uas muab lub teeb, ua kua dej, qib 5000 cS muab kev nplua nuj, puv, velvety- kev paub zoo. Nws txo greasiness thaum sau microscopic nto irregularities, tawm hauv daim tawv nqaij mos thiab du rau lub sij hawm ntev.
Anti-Soaping Performance:
Thaum lub sij hawm daim ntawv thov ntawm cream thiab tshuaj pleev ib ce, emulsifiers feem ntau tsim undesirable dawb streaks, feem ntau hu ua "soaping effect." PDMS-5000 cS muaj cov khoom tiv thaiv zoo heev -ua npuas dej thiab tshuaj ntxuav tes. Txawm tias tsis tshua muaj siab, nws txo qis kev ua kom dawb thaum lub sij hawm thov, ua rau kev sib kis tau yooj yim dua, nqus sai dua, thiab zoo dua qub.
Txhim kho daim tawv nqaij tiv thaiv:
Nws siab -molecular- hnyav polymer chains tsim ib tug semi- breathable, hydrophobic tiv thaiv zaj duab xis uas pab khaws cia noo noo thaum tiv thaiv daim tawv nqaij los ntawm sab nraud irritants.
Automotive thiab Tsev Kho Mob
Raws li cov khoom tseem ceeb hauv tsheb thiab cov khoom siv hauv tsev polishing, PDMS-5000 cS yog ib qho yooj yim rau siv, so tawm, thiab buff. Nws ua kom ruaj khov, siab-gloss tiav thaum txhim kho kev puas tsuaj thiab tiv thaiv cov pleev xim thiab cov hlau los ntawm cov kua qaub los nag, hluav taws xob ultraviolet, oxidation, thiab tshuaj tua kab mob.
Industrial Defoaming thiab Pwm tso tawm
Hauv kev tsim roj av, kev ua haujlwm refinery, thiab kev ua tshuaj lom neeg, PDMS-5000 cS yog cov khoom siv zoo tshaj plaws rau kev ua haujlwm siab defoamer formulations.
Tsis yog -Aqueous Defoaming:
Hauv cov txheej txheem tsis yog -aqueous, cov kev ua tau zoo feem ntau pib ntawm kwv yees li 10 ppm, nrog rau kev ua tau zoo tshaj plaws feem ntau ua tiav nyob rau hauv thaj tsam ntawm 1-100 ppm, nyob ntawm kev tsim thiab kev ua haujlwm.
Kev Tshaj Tawm Mould:
Nws lub zog tsis tshua muaj zog ua rau nws ua cov pwm tso tawm zoo rau cov yas thiab elastomers, ua kom yooj yim demolding thaum ua tus du, tsis xws luag -dawb molded nto thiab txo adhesion rau pwm.
IV. Cia thiab kev nyab xeeb
Txawm hais tias PDMS-5000 cS pom muaj toxicity tsawg, nws yuav ua rau qhov muag khaus ib ntus. Cov cuab yeej tiv thaiv tus kheej tsim nyog yuav tsum tau hnav thaum tuav.
Kev cia khoom:
Khaws cov khoom ntim rau hauv cov thawv ntim nruj nreem kaw rau hauv qhov txias, qhuav, thiab zoo- qhov cua qhov chaw, kom deb ntawm qhov chaw cua sov, sparks, thiab qhib nplaim taws.
Lub neej txee:
Lub neej txee pom zoo yog 24 lub hlis txij li hnub tsim khoom thaum khaws cia raws li kev pom zoo.
