Tsawg kawm tias sepiolite fiber yog qhov tseem ceeb rau kev siv hauv ntau yam qhov chaw ua haujlwm ntawm lub ntiaj teb. Nws yog ib qho ntawv thiab magnesium silicate uas muaj cov kab mob zoo heev, thiab nws tuaj yeem siv rau hauv ntau yam khoom thiab kev ua haujlwm kom txo kev npaj, pab tso cov khoom rau hauv qhov chaw, thiab ntxiv qhov ntau thiab qhov tseem ceeb. Hauv Hebei Hezhen Industrial Co., Ltd. peb tau txiav txim siab kom ua qhov chaw siv sepiolite fiber uas muaj kev ntsuas zoo kom cov neeg siv khoom hauv lub ntiaj teb tuaj yeem ua raws li kev ua haujlwm zoo dua. Peb pib tsis tau txog qhov ntawv thiab ua haujlwm rau kev siv hauv 4 qhov chaw tseem ceeb.
Qhov kab mob zoo tshaj plaws uas muaj ib qho kab
Cov kev cim ntawm kev tswj hwm ntawm sepiolite muaj los ntawm nws qhov kev ua haujlwm tsis tuaj yeem ntawm cov nanofiber uas muaj ib dim. Ib qho lub xaim, uas yuav tau siv los txhais rau qhov kev ua haujlwm tseem ceeb ntawm cov khoob, muaj ib qho lub xaim uas muaj cov tetrahedral sheets (SiO4) uas muaj kev sib txuas raws li qhov kev sib txuas ntawm cov zigzag thiab muaj cov magnesium atoms uas muaj kev sib txuas ntawm qhov octahedrally. Cov fiber sib txawv yuav muaj qhov loj ntawm 0.2 μm rau 2 μm nyob rau hauv qhov dav, 100 nm rau 300 nm nyob rau hauv qhov dav, thiab 50 nm rau 100 nm nyob rau hauv qhov ntev.
Cov kab laug no yog loj—loj dua li cas ntawm qhov dav thiab qhov siab, uas ua rau muaj qhov nruab nrab ntawm cov kab laug loj. Qhov no txhawj xyuam rau kev sib koom tes ntawm cov kab laug hauv daim ntawv. Vim tias cov kab laug sib koom tes zoo thiab cov cuab yeej van der Waals, cov kab laug sepiolite uas muaj qhov ntev ntawm nws yuav tau sib koom ua ob los sis, tab sis thaum muaj kev sib koom zoo hauv daim ntawv polar, nws yuav tau sib koom ua ib qho kev sib koom tshwj xeeb thiab tshwj xeeb rau kev sib koom tshwj xeeb uas tsuas cov daim ntawv. Vim tias Hebei Hezhen muaj kev kho cov kab laug thiab kev kho cov khoom zoo, sepiolite yog muaj nyob rau hauv qhov zoo thiab qhov zoo tshwj xeeb.
Kev sib koom thiab Kev sib koom ntawm Thixotropic
Thaum muab tso rau hauv cov dej uas muaj qhov ntsuag (polar) li ntawm dej, cov kab mob sepiolite yuav tso cia tau rau hauv qhov kev tswb (gel network) uas txhais tau qhov ntau dua ntawm qhov kev tswb. Qhov kev tswb yog ua los ntawm cov kab mob uas muaj qhov siab thiab tsis muaj kev tswb (rigid fibers) uas tso cia raws li qhov tswb thiab muaj kev nyha (van der waals forces) thiab kev nyha ntawm cov kab mob. Qhov kev nyha thiab kev tswb rau hauv qhov kev tswb no yog qhov uas muaj kev tswb thixotropic—the system becomes fluid upon application of mechanical energy (shearing or stirring) and progressively recovers its viscous structure at rest. Cov kev tswb sepiolite uas muaj qhov ntau ntawm cov khoom (solids) li 2-3% tuaj yeem muaj kev tswb “aging” uas nyuaj dua, uas muaj kev ntau dua ntawm qhov kev tswb (yield stress) rau hauv ib lub hlis.
Qhov no ua rau cov kab mob zoo rau kev tshuaj tshuaj (formulating) cov kev tswb li cov dej tshuaj thiab cov dej tshuaj tshuaj (coatings) lossis cov dej tshuaj rau kev tshuaj (drilling fluids) uas pab tshuaj tshuaj rau kev tswb rau kev tswb (sag resistance) thiab pab tshuaj tshuaj rau kev tswb (settlement).
Kev tswb rau hauv cov solvent systems sib txawv
Sepiolite fiber ua lub tswv yim uas qhia cov ntaub ntawv uas muaj kev sib koom tes tsis yog rau cov system uas muaj dej xwb, tab sis kuj muaj kev nyab xa rau cov system organic ntau yam. Raws li cov kab laug uas muaj dej thiab cov qhov chaw uas muaj dej, sepiolite yuav tshwm sim los ntawm cov ntaub ntawv thiab ua cov gel uas muaj kev ncaj ncees rau hais cov ntaub ntawv uas muaj qhov ntau tshaj plaws. Cov lus qhia ntawm sepiolite gel yog txhawb los ntawm cov lus qhia ntau yam, zoo li pH, kev ncaj ncees ntawm cov ion, cov ntaub ntawv ntxhiab rau hais cov ntaub ntawv, thiab yuav sib txawv heev raws li cov lus qhia no. Cov lus qhia ntawm yield stress yuav ncaj ncees rau hais cov ntaub ntawv thiab rau hais cov cim ntau dua, tab sis cov lus qhia yuav tshwm sim rau hais cov ntaub ntawv ntau dua. Rau hais cov ntaub ntawv uas muaj oil, sepiolite yuav tsum tau txais kev txiav txim rau hais cov ntaub ntawv uas tsis muaj dej rau hais cov ntaub ntawv uas tsis muaj dej. Piv txwv li, sepiolite uas tau txais kev txiav txim (organo-sepiolite) yuav muaj kev sib koom tes zoo dua rau hais cov ntaub ntawv uas tau txais kev sib koom tes rau 180°C rau 16 teev thaum cov ntaub ntawv tsis tau txais kev txiav txim. Cov lus qhia hais tias sepiolite muaj kev nyab xa rau hais cov cim ntau thiab rau hais cov ntaub ntawv uas muaj dej yuav pab rau hais cov ntaub ntawv uas muaj oil thiab cov ntaub ntawv uas muaj dej.
Cov kev siv tau thiab cov kev pab rau hauv qhov chaw sib tshuaj
Cov kev pab ntawm sepiolite fibers yog muaj nyob rau hauv ntau qhov txheej txheem. Piv txwv li, nws tuaj yeem pab tshem cov cua thiab pab lub cev ntawm lub tshuab los ntawm kev sib xyaw lub tshuab thiab gas. Cov duab ntawm kev kho tshuab rau hauv cov tshuab loj yuav tau pab los ntawm kev nyuaj ntawm kev nyuaj thiab kev nyuaj rau cov duab ntawm cov duab. Sepiolite fiber tuaj yeem ua lub tshuab thiab lub tshuab rau hauv cov duab cement, cov duab cement grouts, cov duab tshuab tshuab—Hebei Hezhen tuaj yeem tsim cov duab no raws li, cov duab, cov duab, cov duab tshuab, cov duab polymer composite materials, thiab lwm yam. Rau Hebei Hezhen Industrial Co., Ltd., peb paub tias peb muaj cov khoom zoo thiab cov khoom uas muaj qhov siab uas yuav raug rau cov neeg siv los ntawm peb cov kev tsim khoom uas muaj ISO9001:2000, cov neeg tsim khoom uas muaj ntau zaus (ntau dua 60 tus), cov tsev tsim khoom, cov tsev test khoom, cov tsev kho khoom, cov tsev kho khoom thiab cov tsev kho khoom.
