Ukulungiselela isampuli

Yintoni ebalulekileyo?

Ngaphambi kokuhamba, kubalulekile ukugqiba ukuba ingaba isampuli iyakwazi ukuqhutyelwa ngqo okanye ingaba unyango lwangaphambili luyimfuneko. Izinto ezinjengokufuma, ukuhlanganisana, ukusasazwa kokungalingani, okanye izinto zangaphandle zinokuthintela inkqubo kwaye zikhokelela kwiziphumo ezingachanekanga.

Ubungakanani besampulu efunekayo kufuneka kwakhona kuthathelwe ingqalelo: Zingakanani izinto ezifunekayo kuhlalutyo olulandelayo, kwaye ingakanani isampuli yokuqala? Ukuba kuyimfuneko, i-subsample yommeli kufuneka ithathwe ukwakheka kwayo kuhambelana nesampuli iyonke.

Isampuli

Uninzi lweesampulu zaselabhorethri ziyimixube engalinganiyo. Ubukhulu bamasuntswana ahlukeneyo kunye nokuxinana kwezinto kudla ngokukhokelela ekuhlukaneni ngexesha lokuthutha kunye nokuphatha. Ukuba isampuli yonke ayinamhlaba, isampuli yommeli kufuneka ithathwe.

Ukuba isampulu yokuqala inkulu kakhulu, kufuneka icolwe kwangaphambili phambi kokwahlulwa. Ukukhethwa kwendlela efanelekileyo yokwahlula kunye nesixhobo kuxhomekeke kwizinto eziphathekayo kunye nomthamo wesampuli efunekayo. Ukuhamba ngokukhululekileyo, iisampulu ezomileyo zinokwahlulwa kusetyenziswa, umzekelo, i-feeders, i-rotary tube dividers, okanye izahluli ezikhethekileyo zesampulu kwizinto ezininzi, ngelixa i-fluted dividers zifanelekile kwizinto ezincinci ezihamba ngokukhululekile.

I-manual, isampuli ehleliweyo ifanelekile ngokukodwa xa kuhlalutya kuphela uhlalutyo olulula, i-material i-homogeneous ngokwaneleyo okanye ayikho enye indlela enokwenzeka ngenxa yeengxaki zexesha.

Isampulu yesampulu ejikelezayo

Izahluli zethu zesampulu ezijikelezayo zenzelwe ngokukodwa ulwahlulo kunye nokunciphisa umthamo wezinto ezininzi ezinomgubo okanye zegranular.

Ukuqwayita

Ukudityaniswa kwezinto zesampulu ezifumileyo okanye ezimanzi—umzekelo, kwizityuli zemihlathi, ii<em>rotor Mills, okanye ii<em>cutting Mills — kudla ngokuba nzima. Ubumanzi bunokukhokelela ngokukhawuleza kwiibhlokhi kwigumbi lokusila, kubangela ukuba i-ring and bottom sieves idumbe, kwaye ekugqibeleni ivimbe isixhobo. Oku akubanga nje ukulahlekelwa kwezinto eziphathekayo kodwa kwandisa umgudu wokucoca.

Okungaphandle kubandakanya iinkqubo ezinjengokugaya i-colloidal, apho ulwelo longezwa ngabom kwiibhola zebhola, kunye ne-homogenization yeziqhamo ezitsha kunye nemifuno, apho kungekho nto ilahlekileyo.

Kwiimeko ezininzi, nangona kunjalo, kuyimfuneko ukomisa iisampulu ezifumileyo ngaphambi kokugaya. Xa ukhetha indlela yokumisa efanelekileyo, ngaphezu kwendawo yokubilisa, iingozi ezinokubakho ezifana nokusebenza kwakhona, ukuqhuma kothuli, okanye ubushushu bobushushu bezinto ezithile kufuneka ziqwalaselwe. Izilumkiso ezifanelekileyo zokhuseleko zibaluleke kakhulu kwizinto ezifana ne-polychlorinated biphenyls (PCBs) okanye ii-dioxins.

Iidiphozithi zesinyithi

Iisampulu ezininzi, ingakumbi kwicandelo lokusingqongileyo elifana nenkunkuma yorhwebo, imathiriyeli eshiyekileyo, amafutha esibini kunye nenkunkuma yokulahla inkunkuma, ihlala iqulathe amacandelo esinyithi angenako ukucolwa kusetyenziswa isixhobo esicetywayo sokukrazula.

Enyanisweni, izinto zangaphandle ezifana nezikhonkwane zentsimbi okanye izikrufu zentsimbi zingonakalisa izixhobo zokugaya kwaye ngaloo ndlela ziphazamise kakhulu ukusebenza kwelitye. Ngenxa yesi sizathu, iinxalenye zetsimbi kufuneka zisuswe ngaphambi kokuhlaziywa kwaye, ukuba kuyimfuneko, zilahlwe.

Ukusetyenziswa kwe-nitrogen engamanzi kwi-cryogenic yokusila okanye ukugaya okubandayo

I-embrittlement nge-nitrogen engamanzi okanye umkhenkce owomileyo

Ukupholisa imathiriyeli ukuba ibe ngumhlaba kaninzi kuphucula ukuziphatha kwayo kokuqhekeka. Ukupholisa okunzulu, okuthe ngqo kuyafuneka ekusileni kwangaphambili kunye nokucolwa kakuhle kweesampulu ezingevayo kubushushu, njengeeplastiki ezininzi. Enye inketho ku-embrittle imbrittle material in liquid nitrogen (N₂, LN₂) ngaphambi kokugaya. Ngaphandle koko, inokupholiswa ngeqhwa elomileyo, ukwenzela ukuba izinto eziphathekayo zibe brittle kumaqondo aphantsi kwaye kulula ukugaya.Ukugaya i-Cryogenic)

Iindlela zokupholisa zikwasetyenziswa xa amacandelo aguquguqukayo kwisampulu kufuneka agcinwe. Isizathu salokhu kubushushu obuphantsi apho, ngokomzekelo, umswakama kwizinto zesampulu ziqina zibe ngumkhenkce kwaye awukwazi ukubaleka ngexesha lokugaya. Emva kokusila, amanzi angumkhenkce aphinda anyibilike kubushushu begumbi. Ngoko ke, kusoloko kubalulekile ukujonga ukuba indlela ekhethiweyo ishiya ukubunjwa kwesampuli ingatshintshi.

Imibuzo ebuzwa rhoqo

Ukugaya i-Cryogenic yindlela ethambileyo yokuhambisa kunye ne-homogenizing iisampulu zeqondo lokushisa. Iimathiriyeli zipholiswa kusetyenziswa izipholisi ezibanda kakhulu, nto leyo ezenza zibe brittle kwaye zenze ukuba zikwazi ukusebenza ngoomatshini.

Inzuzo ephambili yokugaya i-cryogenic kukuba izinto ezithintekayo kwiqondo lokushisa zinokucutshungulwa ngaphandle kokusetyenziswa kobushushu. Oku kubangela ukuziphatha okuphuculweyo kokuqhekeka kwaye kwenza ukuhanjiswa kwezinto ezinzima okanye ezingenakwenzeka ukucubungula ngomatshini phantsi kweemeko eziqhelekileyo, ezifana ne-elastomers.

Izizipholisi eziqhele ukusetyenziswa yinitrogen elulwelo (malunga no -196 °C) kunye nomkhenkce owomileyo (malunga no -78 °C). Ezi ziqinisekisa ukupholisa ngokukhawuleza, ukukhupha izinto zesampulu, kwaye ngaloo ndlela kuphuculwe inkqubo yokukhupha.
