Qhov sib npaug ntawm daim txhuam cev

- Aug 17, 2018-

Kev lag luam qho khoom nruab nrab ntawm cov phom yog raws li qhov ceev. Qhov ntom ntawm cov daim txhuam cev yog kg / m3. Nws yog qhov nyhav ntawm txhua txhua tus cubic meter ntawm daim txhuam cev. Kev ceev yog ib qho tseem ceeb ntawm qhov teeb meem, thiab qhov ceev ntawm lub daim txhuam cev yog siab, qhia tias qhov sib txawv hauv lub me me yog qhov zoo dua. Piv txwv: 40 ntom txhais tau hais tias qhov nyhav ntawm qhov cubic meter sponge yog 40 kg, thiab qhov ceev ntawm 50 yog 50 kg ntawm ib lub ntsuas kub (cubic meter). Feem ntau hais lus, cov kab nrig uas muaj qhov kub ceev yog qhov tseem ceeb hauv kev nyuaj, tab sis nws tsis yog tshem tawm tias qee qhov kev kub ntxhov yuav ntxiv cov khoom siv super soft los ua daim iav sponge super, uas yog siv rau lub suab paj nruag, rooj zaum lub ncoo thiab lub hnab muag khoom. Medium thiab low density sponges yog siv los ua cov ntaub ntawv tiv thaiv.


Lub degree ntawm hardness ntawm sponge ntawm tib ceev yog tsis tas tib yam. Feem ntau, qhov ceev ntawm daim txhuam cev rau lub rooj zaum khawm yog 35, thiab nws muaj qhov muag muag, nyuaj, super mos thiab lwm yam. Lub txaj yog li ntawm 22 feet. Cov lus sib dhos ua ke yog lub sij hawm feem ntau siv los ntawm cov neeg muag khoom thaum muag khoom. Raws li kev piav qhia ntawm lub xeev cov tuam tsev, qhov ceev yog ≥ 45 rau qhov siab ceev, qhov kub ceev yog <45 thiab=""> 18, thiab qhov qis qis <>
