COD YOPHUNZITSIRA MALO OGULITSIRA

Zipangizo zaCOD YOPHUNZIRANthawi zambiri amasaka kwambiri, osalowerera ndale, komanso borrosil. Zitha kugwiritsidwa ntchito ngati palibe mawonekedwe osafunikira. Madzi ochepa kugaya ndi utotome ikafunika, zinthu zosankhidwa sizimalowerera ndale.

Pali mitundu itatu ya zinthu za chivindikiro: yoyera polypropylene ya nthawi imodzi; kuwonekera Polycarbonate yogwiritsa ntchito mobwerezabwereza; Kukhazikika kwa phenolic kuti mugwiritse ntchito machubu oyeserera mobwerezabwereza pamwamba 110mm.

Kuti mumve zambiri pa machubu a cod ndi mapulogalamu awo pakuwunika kwamadzi, onani nkhani iyi:"Momwe COBE YOPHUNZIRA YA COD imagwiritsidwa ntchito powunikira madzi."

Chinsinsi cha Kugaya

1. Gwiritsani ntchito chida chaching'ono chomwe chikufanana ndi chubu. Mabotolo ozungulira amafanana ndi zida zozungulira pansi, ndipo mabotolo athyathyathya amafanana ndi zida zapamwamba. Kupanda kutero, kutentha kosasinthika kumadzetsa chubu. Mukayika chubu choyeserera, iyenera kuyikidwa pang'onopang'ono kuti ipewe kugunda mwamphamvu kwa chubu chambiri cha chubu ndi chimbudzi. Malinga ndi zomwe zidachitika m'mbuyomu, mababu ena a chimbudzi amaphulika chifukwa chogwira ntchito molakwika.

2. Pewani kugwiritsa ntchito machubu ndi zingwe zokhala ndi ulusi wokhazikika. Malawi sasindikiza ndikutulutsa. Zimatengera kuti zimakhala zosalala mukapotoza. Yosalala ndi yosalala ndipo chivindikiro sichimangokhala osokonekera kwambiri kuti akwaniritse zofunika.

3. Pewani zikwangwani zambiri. Machubu ndi machubu adzakupusitsidwa popukutirana wina ndi mnzake. Kuyeretsa botolo ndikosavuta kubweretsa zipsera. Kupukusa ndi malingaliro ofooka a mphamvu ya chubu.

4. Pewani kugwiritsa ntchito mabotolo ndi zingwe zowonongeka. Chifukwa cha kulowererapo kwamanja nthawi yoyendera, zinthu zotere ndizosapeweka. Osagwiritsa ntchito mabotolo ndi zitsulo ndi chilema.

5. Osamagaya zitsanzo zamadzi mwachindunji. Muyenera kukhala ndi ma reagents ofanana. Malo otentha amadzi ndi otsika kwambiri. Madzi ochulukirapo omwe alipo, ochulukanso omwe ali mu botolo adzakhala, ndipo chivundikiro sichitha kugwira. Ngati mukufuna kugaya zitsanzo zambiri zamadzi, chonde gwiritsani ntchito chivindikiro chochuluka komanso chofiyira.

6. Kukwaniritsa cholinga cha Cod Index ndi zitsanzo zamadzi monga zitsanzo, popeza mankhwala ena a Sufuric acid ndi mankhwala ena a sulfuric sayenera kuwira mu chimbudzi ndi kuwononga chubu. Chifukwa chake, makina amadzi ayenera kusakanikirana kwambiri chisanachitike kuti atetezeke chubucho kuti chisagwedezeke.

Kufanizira Kusamala

1. Gwedezani bwino asanafanane. Musanayike chubu choyesera mu chithunzi, kupukuta chubu choyeserera ndi nsalu yoyesera.

2. Sankhani chida chosinthika komanso chida chachikutira chokhala ndi cholakwika chaching'ono kuti mupewe zolakwika zambiri zomwe zimayambitsidwa ndi zida ndi zida.

3. Ngati pali zikwangwani, osagwirizana ndi mawonekedwe ake ndi mawonekedwe.

4. Pakugama mwachangu kwambiri, chofunikira kwa chubucho ndikuti kulakwitsa kwa utoto kuli mkati mwa ± 0,005, ndiye kuti, mkati mwa magawo 10, motero aphungu a batch omwewo ayenera kukhala olakwika momwe mungathere. Ngati 20% ya machubu mu batchi olakwika, machubu a mtundu wa batch iyi siali osavomerezeka.

5. Chonde gwiritsani ntchito madzi oyera kuyesa cholakwika cha chubu.

[Malangizo a Farmimetric Fareisonc]

Pamene ma utonimetric kuyerekezera mbali imodzi, chifukwa ndikosavuta kukhala ndi zolakwa pamitengo yokwanira komanso yocheperako, kapena zitha kungochitika kuti mawonekedwe omwe mukuyesa ali ndi fumbi kapena fumbi. Ndikofunika kuyesa mbali zitatu ndi chubu chomwecho. Ngati malingaliro a malo atatu ali mkati mwa ± 0,005, gwiritsani ntchito mfundo zitatuzi kuti zitheke ngati zotsatira zoyeserera. Izi zimaletsa zolakwika zomwe zimayambitsidwa chifukwa chomukhumudwitsa ndikupewa kulandira mtengo wokwanira wa chubu. Ngati chubu chomwechi chimatengedwa kupitilira kasanu ndi chimodzi koma osapeza zinthu zitatu mkati mwa ± 0,005, ndiye kuti pali vuto ndi chubu ichi (joble silabwino).

Kuti mumvetsetse momwe ma Cilod a Cials amagwiritsa ntchito magetsi, chonde onani nkhaniyi:"Mfundo yogwira ntchito ya cod vial. "
