Kutentha kwa mpweya ndi chinyezi panthawi yowumitsa nkhuni

 Njira yowumitsa matabwa ocheka kapena magawo omalizidwa mu zowumitsira ikuchitika chifukwa cha kutentha komwe kumawachitira, chinyezi komanso kuthamanga kwa mpweya, komwe kumatchedwa kuti kuyanika.

Pakuuma kwa nkhuni, kutentha ndi chinyezi cha mpweya zimasintha. Kumayambiriro kwa kuyanika, monga lamulo, kutentha kochepa ndi kutentha kwa mpweya kumakhazikitsidwa - pali kusiyana kochepa pakati pa kuwerenga pa thermometer youma ndi yonyowa. Kumapeto kwa kuyanika, kutentha kwakukulu, chinyezi chochepa cha mpweya ndi kusiyana kwakukulu pakati pa kuwerenga pa thermometer youma ndi yonyowa amaperekedwa. Kusiyana kwakukulu pakati pa zowerengera pa bulbu youma ndi yonyowa, ndizovuta kwambiri kulamulira kowumitsa kudzakhala ndi miyeso yofanana, mtundu ndi chikhalidwe cha zinthu zomwe ziyenera kuuma, kumanga chowumitsira ndi zofunikira zomwe zimayikidwa pa khalidwe la zinthu zouma. Kuuma kwa ulamuliro wowumitsa kumatha kuweruzidwa poyerekeza ndi nthawi yowuma yanthawi zonse. Ngati mawonekedwe operekedwawo ndi ofupikitsa kuposa nthawi yowumitsa, ndiye kuti ndizovuta kwambiri.

Pa kuyanika, chinyezi ndi kupsinjika kwa nkhuni zowumitsidwa ziyenera kuyendetsedwa. Chinyezi chimalamuliridwa ndi kuyeza nthawi ndi nthawi chitsanzo cha nkhuni mu chipinda chowumitsira. Kupsyinjika kapena kupanikizika komwe kumachitika mu nkhuni zowumitsa kumayendetsedwa poyang'ana khalidwe la mafoloko oyesera (mkuyu 1), odulidwa kuchokera ku chitsanzo chowongolera, chomwe chimapezeka mu chowumitsa. Chifukwa chake, kutengera kupsinjika komwe kumachitika pazinthu zowumitsidwa, chithandizo choyenera cha hydrometric cha nkhuni zowuma chimagwiritsidwa ntchito. Kupsinjika kwamphamvu, komwe kumayambitsa ming'alu yakunja, kumachitika nthawi zambiri. Pankhaniyi, kukonza zinthuzo ndi mpweya ndi chinyezi chowonjezereka komanso kutentha kwakukulu kumagwiritsidwa ntchito. Monga lamulo, mankhwalawa amachitidwa pambuyo pouma nkhuni kufika pa chinyezi cha 23 - 30%. Kuchiza kwa mpweya pakuwonjezeka kwa chinyezi ndi kutentha kokwezeka kumagwiritsidwa ntchito powumitsa mitengo yamitengo yolimba komanso zigawo zazikulu zamitengo yamitengo ya coniferous.

Chithunzi No. 1 - Mafoloko oyesera: a - kupsinjika kwamphamvu mu zigawo zakunja ndi kupsinjika kwamkati mkati;

b - kuthamanga pamwamba ndi kusagwirizana pakati pa zone; c - chitsanzo chabwino

Monga chitsogozo, nthawi ya chithandizo ichi wapakatikati akhoza akulimbikitsidwa paini ndi spruce nkhuni kwa 4 - 5 maola 25 mm makulidwe, ndi birch 6 - 8 hours.

Kutentha ndi chinyezi cha mpweya wotentha mu chowumitsira zimayesedwa ndi psychrometer, yomwe imakhala ndi ma thermometers awiri - owuma ndi onyowa, omwe amawerengera chinyezi cha mlengalenga angapezeke, pogwiritsa ntchito zithunzi kapena matebulo apadera.

M'chipinda chowumitsa, njira yokhazikitsira imatha kusungidwa mosavuta ngati palibe kutentha komwe kumatayika ndipo ngati mpweya wabwino komanso kutulutsa mpweya wodzaza ndi nthunzi wamadzi kumachitika bwino. Chifukwa chake, chowumitsira chowumitsira chiyenera kutsekedwa ndi hermetically. Zitseko, makoma ndi denga ziyenera kusunga kutentha mu chowumitsira, ndipo mipiringidzo ndi utsi ayenera mosalekeza kupereka mpweya wabwino ndi utsi mpweya wodzaza ndi nthunzi madzi. Kusankha kwanzeru kamangidwe ka zitseko ndi kutseka Chalk kwa zowumitsa, komanso kukonza mwadongosolo zowumitsira ndi bungwe la anakonza ndi zodzitetezera kukonzanso kuonetsetsa chuma ndi yachibadwa kuyanika zipangizo.
