01 Keeb kwm ntawm miv litter
Cov miv tam sim no nyob hauv tib lub ru tsev tib neeg, tab sis ua ntej xyoo pua 20th, tib neeg thiab miv tsuas yog nyob rau hauv "nodding kev sib raug zoo" thiab tsis tau coj mus rau hauv tsev.
Ib qho laj thawj loj tshaj plaws yog cov miv muaj qhov tsis txaus ntseeg EMMs hauv ntiaj teb... Excrement, Kuv ntseeg tias txhua tus neeg ua haujlwm shovel yuav tsum muaj kev nkag siab tob.Miv yog cov neeg noj nqaij dawb huv, thiab lawv cov poj koob yawm txwv nyob hauv cov suab puam ntawm Africa, uas qhuav heev, uas ua rau nws tsim nyog rau lawv kaw dej hauv lawv lub cev kom ntau li ntau tau.
Yog li ntawd, lawv tso zis ntau ntau ntawm cov zis, thaum feline quav yog fermented, incompletely digested high-protein khoom uas saj heev yooj yim thiab tsis kaj siab.Tab sis miv nyiam kev huv thiab "paub txog kev coj cwj pwm", lawv yuav xaiv qhov chaw zais rau "mus rau hauv chav dej" thiab faus lawv cov excrement hauv xuab zeb.Tab sis txawm tias miv yog cov miv zoo uas nyiam kev huv, cov xuab zeb tsis huv heev, uas ua rau tib neeg tsis tuaj yeem hloov cov miv mus rau hauv cov tsiaj loj.
Nws tsis yog txog xyoo 1947 uas miv litter tau yug los, thiab tib neeg-miv txoj kev npaj ua kom zoo dua.Nws yog ib hnub nyob rau lub Ib Hlis Ntuj xyoo 1947, thiab nws tau txias heev uas txoj kev ntog tag nrho.Ms. Kay Dressa quaj quaj hauv tsev, tsis muaj xuab zeb khawb sab nraum, thiab tsev neeg miv tau ua teeb meem mus rau chav dej.Thaum kawg, nws tau khob qhov rooj ntawm nws tus neeg nyob ze lub tsev Ed Roy kom pab.
Ed Roy khiav lub Hoobkas uas tsim cov xuab zeb thiab ntoo chips, thiab Kay xav kom nws xaj xuab zeb mus tso quav rau miv.Ed generously muab nws lub ntuj av nplaum nrog adsorption zoo heev.Kai zoo siab txais tos, cov nyhuv yog qhov xav tsis thoob zoo, cov av nplaum no muaj qee qhov nqus dej, tuaj yeem nqus cov zis tso zis.Dab tsi yog qhov xav tsis thoob yog tias nws tuaj yeem npog qhov tsis hnov tsw ntawm miv poop rau qee yam.Txij thaum ntawd los, miv litter tau yug los thiab nrawm nrawm thoob ntiaj teb.

Txij thaum ntawd los, tib neeg tau zoo siab khiav tawm ntawm txoj kev mus rau kev tsim cov miv litter tshiab.Piv txwv li, txawm hais tias bentonite miv litter yog qhov yooj yim, tib neeg tau nug nws sai sai vim tias nws muaj plua plav thiab ua rau ib puag ncig kev nyiam huv hauv tsev.Tom qab ntawd, tib neeg tau tsim cov miv litter tshiab: xws li tofu miv litter, siv lead ua miv litter, ntoo thuv miv litter, pob kws miv litter, nplej miv litter, thiab lwm yam.
Nyob rau hauv qhov tseeb, bentonite miv litter ntawm tag nrho cov miv litter, ko taw xav tias ze tshaj plaws rau lub ntuj qub, miv nrog bentonite miv litter, ib yam li rov qab mus rau qhov xwm txheej.Yog li ntawd, lawv yog kiag li unresistant rau bentonite miv litter.Tab sis txog tam sim no, ntau tus neeg ua haujlwm shovel rau bentonite miv litter daim ntawv lo yog "plua plav", qhov tseeb, nrog kev txhim kho txuas ntxiv thiab kev nce qib ntawm cov cuab yeej siv tshuab miv litter, qee qhov high-end bentonite miv litter tau tuaj yeem txo cov plua plav mus rau ib qho. qib qis, yuav luag tsis muaj plua plav.
03 Kev faib tawm ntawm bentonite miv litter
Bentonite muab faib ua calcium-based bentonite thiab sodium-based bentonite.Txawm li cas los xij, qhov nyuaj, adsorption thiab qhwv ntawm calcium-based bentonite yog qhov phem dua li ntawm sodium-based bentonite, thiab feem ntau ntawm cov khoom siv raw ntawm high-end bentonite miv litter ntawm lub khw yog sodium-based bentonite.04 Lub tsev bentonite miv litter lag luam raug ntes nyob rau hauv tus nqi tsov rog.
Ntawm qhov tod tes, kev lag luam hauv tsev yog dominated los ntawm bentonite xuab zeb, tofu litter noj yog loj hlob sai thiab sai, thiab lwm yam kev lag luam qauv ntxiv, miv litter nqi tsov rog tau mob hnyav rau tag nrho kev lag luam.Noj bentonite xuab zeb ua piv txwv, muaj ntau lub tuam txhab bentonite miv litter lag luam hauv Ningcheng County, Inner Mongolia, ntxiv rau Chaoyang, Jinzhou, Hebei hauv Liaoning, cov tuam txhab loj thiab me nyob ze rau kaum tawm thiab ze li ntau pua, tus nqi tau nqis los ntawm 3000 yuan. mus txog 1500 yuan ib tuj, thiab cov tuam txhab tsim khoom yuav luag tsis muaj txiaj ntsig.Txawm hais tias lub tuam txhab tofu xuab zeb tsis tau tshawb xyuas tshwj xeeb, tus nqi tau nqis los ntawm 9,500 yuan ib tuj mus txog 5,000 yuan, uas yog ze rau qhov xwm txheej tam sim no ntawm bentonite miv litter.Xyoo no, vim muaj kev sib kis, kev ua lag luam ntawm cov chaw tsim khoom hauv av thiab cov chaw tsim khoom pelletizing av tau poob qis, thiab qee qhov ntawm cov chaw tsim khoom no yuav hloov mus rau miv litter, thiab qhov sib txawv ntawm kev muag khoom hauv khw tau nce ntxiv.Ntawm qhov tod tes, los ntawm kev xav ntawm kev lag luam thoob ntiaj teb, kev ua tsov ua rog ntawm Tuam Tshoj txoj kev lag luam hauv tsev tau raug xa mus rau thoob ntiaj teb kev ua lag luam, thiab tus nqi ntawm kev ua lag luam thoob ntiaj teb tau qhia ncaj qha rau kev sib tw.
