I-HEC yeengubo ezisekelwe emanzini

Yazisa:

Kwiminyaka yakutshanje, iingubo ezisekelwe emanzini ziye zafumana ukuthandwa ngenxa yobuhlobo babo bokusingqongileyo kunye nomxholo ophantsi we-volatile organic compound (VOC). Esinye isithako esibalulekileyo esidlala indima ebalulekileyo kwimixube yokwaleka esebenza kakhulu emanzini zizongezo zodidi oluphezulu lwe-coalescent (HECs).

1. Qonda iingubo ezisekelwe emanzini:

A. Isishwankathelo sokwaleka esekwe emanzini

b. Izibonelelo zokusingqongileyo zokugquma kwamanzi

C. Imiceli mngeni ekuqulunqeni imigangatho ephezulu yokwaleka kwamanzi

2. Intshayelelo kwizongezo ezenza ifilimu ezisebenza kakuhle kakhulu (HEC):

A. Inkcazo kunye neempawu ze-HEC

b. Uphuhliso lwembali kunye nokuziphendukela kwe-HEC

C. Ukubaluleka kwe-coalescence kwiingubo ezisekelwe emanzini

3. Indima ye-HEC kwinkqubo yomanyano:

A. Ukubambisana kunye neendlela zokuqulunqa iifilimu

b. Impembelelo ye-HEC kwi-particle coalescence kunye nokuthembeka kwefilimu

C. Ukuphucula ukubambelela kunye nokuqina kunye ne-HEC

4. Uphuculo lokusebenza kweHEC:

A. Ukuqulunqwa kwefilimu kunye nexesha lokumisa

b. Impembelelo kwizinga kunye nenkangeleko

C. Impembelelo yobulukhuni kunye nokumelana nokunxiba

5. Imiba yozinzo lwe-HEC kwiingubo ezisekelwe emanzini:

A. Ukunciphisa i-VOC kunye nefuthe lokusingqongileyo

b. Ukuthotyelwa kwemigaqo kunye nemigangatho yehlabathi

C. Uhlalutyo lomjikelezo wobomi be-HEC yokwaleka kwamanzi

6. Izicelo zeHEC kumashishini ahlukeneyo:

A. Iingubo zoKwakha

b. Iingubo zeemoto

C. Iingubo zeemveliso

d. Iingubo zokhuni

7. Imingeni kunye nophuhliso lwexesha elizayo:

A. Imingeni ekhoyo ngoku kuCwangciso lwe-HEC

b. Iindlela ezivelayo kunye nezinto ezintsha

C. Amathemba ekamva le-HEC kwiingubo ezisekelwe emanzini

8. Imizekelo kunye nemizekelo:

A. Ukusetyenziswa ngempumelelo kwe-HEC kwiimeko zokwenene

b. Uhlalutyo lokuthelekisa kunye nezinye izongezo ezenza ifilimu

C. IziFundo eziFundiweyo kunye neeNgcebiso zoPhuhliso

ukuququmbela:

Ukushwankathela iingongoma eziphambili ezixutyushwa kweli nqaku, sigxininisa indima ephambili ye-HEC ekuphuculeni ukusebenza kunye nokuzinza kweengubo zamanzi. Amandla okuqhubela phambili uphando kunye nophuhliso kulo mmandla abonakalisiwe.
