PP/PVC萃取槽一般使用要在室內(nèi)，恒溫在20℃～50℃之間，收縮膨脹系數(shù)大，要連續(xù)使用，注意不能用用停停，這樣容易產(chǎn)生斷裂現(xiàn)象。平時(shí)使用時(shí)，保持清潔美觀。需要改動(dòng)時(shí)，抽空局部料液，洗凈擦干，局部改動(dòng)焊接。如發(fā)現(xiàn)串級(jí)滲漏現(xiàn)象需要修補(bǔ)時(shí)，要停車、抽液、洗凈，然后再焊接補(bǔ)漏，試水不漏后再恢復(fù)使用。

PP / PVC extraction tank is generally used indoors, with constant temperature between 20 ℃ ~ 50 ℃ and large coefficient of shrinkage and expansion. It should be used continuously. Note that it can not be used or stopped, which is easy to cause fracture. Keep clean and beautiful during normal use. When it is necessary to change, evacuate the local material liquid, wash and dry, and change the welding locally. If it is found that cascade leakage needs to be repaired, it shall be stopped, pumped and cleaned, and then welded to make up the leakage. After the water test is not leaked, it can be restored to use
