Embodiment 1

[0039] This embodiment provides an evaluation of the anti-mold effect of a polymer anti-mold liquid

[0040] Prepare the anti-mold identification swab on site according to the above method, take an appropriate amount of anti-mold liquid to be tested in a spray bottle, spray the anti-mold liquid to be tested evenly on the surface of the anti-mold identification swab, and spray the weight of the anti-mold liquid to be tested for the anti-mold identification 5% of swab weight. Put the sprayed sample into a sealed tank, and then put it in a constant temperature and humidity box and culture it under the condition of light for 72 hours, and take 5 groups of samples for parallel experiments.

Embodiment 2

[0042] This embodiment provides an evaluation of the anti-mildew effect of a mildew-proof ABS board

[0043]Prepare anti-mold identification swabs on site according to the above method, and paste them with anti-mold ABS boards with a size of 50mm×50mm. The anti-mildew identification swab is tightly attached to the sample to be tested by pressing a weight or sticking it. Put the bonded sample into a sealed jar, and then place it in a constant temperature and humidity box for 72 hours of sealed cultivation under the condition of light, and take 5 groups of samples for parallel experiments.

[0044] Such as figure 1 and 2 As shown, the anti-mildew identification swab is bonded to the surface of the ABS plate with anti-mildew function. The surface is clean before the sealed contact culture. After 72 hours of the sealed contact culture, the surface color turns yellow and green, and there are also lumps of bean curd. or mushy.

Embodiment 3

[0046] This embodiment provides a mildew-proof effect evaluation of the mold-proof PE film

[0047] According to the above method, the anti-mold identification swab was prepared on site, and it was pasted with the anti-mold PE film with a size of 50mm×50mm. The anti-mildew identification swab is tightly attached to the sample to be tested by pressing a weight or sticking it. Put the bonded sample into a sealed jar, and then place it in a constant temperature and humidity box for 72 hours of sealed cultivation under the condition of light, and take 5 groups of samples for parallel experiments.

Abstract

The invention discloses a mildew-proof identification swab as well as a preparation method, a use method and application thereof, and belongs to the technical field of efficacy evaluation. The mildewproof identification swab is prepared by taking milk rich in animal protein or soymilk rich in plant protein as a bacterial carrier and a bacterial carrier supporting material polypropylene non-woven fabric, uniformly mixing the bacterial carrier raw material and water at 40-60 DEG C according to a mass ratio of 1: (6-8) in a clean environment at room temperature, cooling to room temperature, and packaging to obtain the mildewproof identification swab. And uniformly spraying the mixture which is 1.25 times of the weight of the bacterial carrier supporting material on the surface of the bacterial carrier supporting material until the mixture is completely absorbed. After a sample to be detected is in full contact with the mildew-proof identification swab, the sample is subjected to sealed contact culture for 72 hours under the conditions of constant temperature, constant humidity and illumination, and the mildew-proof effect of the sample to be detected is subjected to sensory evaluation. Compared with a traditional mildew-proof test, the mildew-proof identification swab for evaluating the mildew-proof effect has the advantages of being short in period, high in timeliness, visual in result, wide in application, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of efficacy evaluation, and in particular relates to an anti-mildew identification swab and its preparation method, use method and application. Background technique [0002] There are many kinds of microorganisms with different habits, and the types of microorganisms growing on various industrial materials or products are also different. The variety and distribution of polluting bacteria in various industrial materials or products change dynamically with changes in environmental conditions, so the dominant bacteria are not constant. As described in the prior art, patent application CN104560726A discloses a method for screening moldy strains of coiled mosquito-repellent incense and an evaluation method for the anti-mildew effect of coiled mosquito-repellent coils. Picking mold spores for single colony isolation, using the mildewed strains of mosquito-repellent coils, and cultivating the mosquito-repellent co...
