1. Kutentha: Kutentha kumakhudza mwachindunji matenthedwe amtundu wa zipangizo zosiyanasiyana zotentha.Pamene kutentha kumawonjezeka, kutentha kwa zinthu kumakwera.

2. Chinyezi: Zida zonse zotetezera kutentha zimakhala ndi porous ndipo zimakhala zosavuta kuyamwa chinyezi.Chinyontho chikakhala chachikulu kuposa 5% ~ 10%, chinyonthocho chimakhala ndi gawo la pore lomwe limadzaza ndi mpweya pambuyo potengera chinyezi, zomwe zimapangitsa kuti matenthedwe ake azitha kuwonjezeka kwambiri.

3. Kachulukidwe kachulukidwe: Kachulukidwe kachulukidwe kachulukidwe kake ndi chithunzithunzi chachindunji cha porosity ya zinthuzo.Popeza kuti kutentha kwa gawo la gasi nthawi zambiri kumakhala kocheperako kuposa gawo lolimba, zida zopangira mafuta zimakhala ndi porosity yayikulu, ndiko kuti, kachulukidwe kakang'ono.Nthawi zonse, kuwonjezera pores kapena kuchepetsa kachulukidwe chochuluka kudzachititsa kuchepa matenthedwe madutsidwe.

4. Tinthu kukula kwa zinthu lotayirira: Pa kutentha kutentha, matenthedwe madutsidwe wa zinthu lotayirira amachepetsa monga tinthu kukula kwa zinthu amachepetsa.Pamene tinthu kukula lalikulu, kukula kwa kusiyana pakati pa particles ukuwonjezeka, ndi matenthedwe madutsidwe mpweya pakati adzakhala mosalephera kuwonjezeka.Zing'onozing'ono kukula kwa tinthu, kumachepetsa kutentha kwa kutentha kwa matenthedwe.

5. Kutentha kwa kayendedwe ka kutentha: Kugwirizana pakati pa kutentha kwa kutentha ndi kayendedwe ka kutentha kumakhalapo kokha mu zipangizo za anisotropic, ndiko kuti, zipangizo zomwe zimakhala ndi zosiyana zosiyanasiyana.Pamene kutentha kutengerapo malangizo ndi perpendicular kwa CHIKWANGWANI malangizo, ndi matenthedwe kutchinjiriza ntchito bwino kuposa pamene kutentha kutengerapo malangizo ndi kufanana ndi CHIKWANGWANI malangizo;mofananamo, ntchito yotetezera kutentha kwa zinthu zomwe zimakhala ndi ma pores ambiri otsekedwa zimakhalanso bwino kuposa zomwe zimakhala ndi ma pores akuluakulu otseguka.Zida za stomatal zimagawidwanso m'mitundu iwiri: chinthu cholimba chokhala ndi thovu ndi tinthu tating'ono tating'ono tating'ono tating'ono.Kuchokera pamalingaliro a makonzedwe a zida za fibrous, pali milandu iwiri: mayendedwe ndi njira yoyendetsera kutentha ndi perpendicular ndi njira ya fiber ndi kayendedwe ka kutentha ndizofanana.Nthawi zambiri, kakonzedwe ka ulusi wa fiber insulation material ndi yotsirizira kapena pafupi ndi yotsirizira.Chofanana kachulukidwe chikhalidwe ndi chimodzi, ndi kutentha conduction The coefficient ndi yaying'ono kuposa matenthedwe madutsidwe wa mitundu ina ya porous kutchinjiriza zipangizo.

6. Chikoka cha kudzaza gasi: Muzinthu zowonongeka zowonongeka, kutentha kwakukulu kumayendetsedwa kuchokera ku mpweya wa pores.Choncho, matenthedwe matenthedwe a zinthu zotetezera amatsimikiziridwa ndi mtundu wa gasi wodzaza.Mu engineering yotsika kutentha, ngati helium kapena haidrojeni yadzazidwa, imatha kuonedwa ngati kuyerekezera koyamba.Amaona kuti matenthedwe madutsidwe wa zinthu insulating ndi lofanana ndi matenthedwe madutsidwe wa mpweya, chifukwa matenthedwe madutsidwe wa helium kapena wa hydrogen ndi lalikulu.

7. Kutentha kwapadera: Kutentha kwapadera kwa zinthu zotetezera kumakhudzana ndi kuzizira (kapena kutentha) komwe kumafunika kuti pakhale kuziziritsa ndi kutenthetsa kwazitsulo zotetezera.Pa kutentha kochepa, kutentha kwapadera kwa zolimba zonse kumasiyana kwambiri.Pansi pa kutentha kwabwino ndi kupanikizika, mpweya wabwino sudutsa 5% ya zinthu zotsekemera, koma kutentha kumatsika, gawo la mpweya likuwonjezeka.Chifukwa chake, izi ziyenera kuganiziridwa powerengera zida zotenthetsera zomwe zimagwira ntchito movutikira.

8. Coefficient of linear expansion: Powerengera kulimba ndi kukhazikika kwa kapangidwe kanyumba mukamazizira (kapena kutentha), ndikofunikira kudziwa coefficient of linear expansion of the insulation material.Ngati mzere wowonjezera wowonjezera wa zinthu zosungunulira zotenthetsera ndizocheperako, kapangidwe kake kazakudya sikungawonongeke chifukwa chakukula kwamafuta ndi kutsika pakagwiritsidwa ntchito.The coefficient of linear extension of most thermal insulation materials amachepetsa kwambiri pamene kutentha kumachepa.
